G2 that brings many innovative solutions. The gadget comes with an almost bezel-less 5.2-inch FullHD display, as well as a 13-megapixel camera with optical stabilization and with high speed shooting. But now about everything in order.
So let's start with the look of the LG G2. The smartphone turned out to be much lighter than we expected, at only 143 grams. It looks just fine, although it is made of glossy plastic and is impressively thin for a battery like this.
Its IPS-screen occupies almost the entire front panel, the bezel has been reduced to only 2.65 mm.
Although the owner of a 5.2-inch display is the largest phone in the company, at the same time, it is quite convenient to operate it with one hand. The new solution lies in the fact that the gadget has not received control buttons on the ends and front panel. The only mechanical control key is located on the back panel under the camera and flash.
Above the display is the speaker, front camera and proximity sensor.
There is nothing on the right side, and on the left there is a slot for a microSIM card. On the top there is a secondary microphone and an infrared sensor.
At the bottom, you can see the main microphone, loudspeaker, 3.5mm headphone jack and microUSB port.
The front and back panels are separated by a very thin silver bezel.
The dimensions of the device are 138.5x70.9x8.9 mm.
Performance and software
The LG G2 is powered by a Qualcomm MSM8974 Snapdragon 800 Krait 400 quad-core processor clocked at 2.3GHz, graphics accelerator Adreno 330 and 2 GB of RAM. 16 or 32 GB are provided (only 24 GB will be available to users) of permanent memory. There is no microSD card slot, although the company said that smartphones with support for memory cards will be supplied to some countries. South Korea such versions will be sold). Operating system - Android 4.2.2 Jelly Bean.
These capabilities allow you to show excellent performance, both when working with conventional and graphical applications.
The device supports work in networks GSM 850/900/1800/1900, HSDPA 850/900/1900/2100, LTE 900/1800/2100/2600/850, GPRS, EDGE. There are Wi-Fi, Bluetooth 4.0, FM radio and GPS / A-GPS modules.
The gadget has preinstalled software: browser, audio player, video player, email client and other applications.
Screen
The picture quality is good, as in the LG Optimus G Pro. Due to its smaller size, the device has a density of 424 ppi, so everything looks perfectly crisp. Colors are vibrant and rich, contrast ratios and viewing angles are excellent. LG G2 has 5.2-inch True HD-IPS display with a resolution of 1920x1080 and 16 million colors. LG's Dual Routing technology has reduced the bezel on the sides of the smartphone to 2.65mm.
A special Cornin Gorilla Glass 3 is used to protect the screen.
Camera
The LG G2 is equipped with a 13-megapixel camera capable of taking photos with a maximum resolution of 4128x3096 pixels, with optical image stabilization, autofocus and LED flash. Photos are of good quality.
The camera is capable of shooting video from Full resolution HD and 60 frames per second.
The camera allows you to shoot HDR photos and has many other features.
The phone also has a 2.1 megapixel front-facing camera for video conferencing. It is capable of capturing Full HD video at up to 30 frames per second.
Battery
The smartphone is equipped with a 3000 mAh non-removable lithium-polymer battery, which will allow the device to work quietly in intensive mode during the day.
At the same time, the company said that in some countries the new product will be sold with a removable battery.

LG G2 video review:
LG was trying to carve out a spot in the big league of Android devices a couple of years ago. And even now, not many people take him seriously, although he makes first-class phones. I considered myself to be such. Although the company released offerings that were comparable to others, for the premium class they lacked something in appearance and functionality that companies such as Nokia and Samsung managed to catch. When LG announced the G2 in 2013, I was still somewhat skeptical if it could compete on an equal footing with the premium smartphones already released to date. Technical specs aside, will the G2 look like a premium smartphone? Find out in today's Review LG G2 D802 32 GB
Design and body
LG has stayed true to its simple tile design with sharpened edges and a glossy back. Despite the 5.2-inch display, the phone is comfortable to hold in the hand, and the slight curvature of the back gives a good grip. I liked the black model more than the white one. The phone lacks buttons on the sides, they were moved to the back panel. Most likely, this was done with the aim of maximally distinguishing from competitors, and was not dictated by the design features of LG, but on the other hand, this does not really interfere.
A Quick Window cutout case will ship as part of LG's original offering.
There is a groove on the side of the phone. microSIM cards, on the upper part there is an infrared port, and below there is a speaker, a connector for microUSB and headphones. The buttons are located under the 13-megapixel camera. Overall, the G2 is a marked improvement over what we've seen from LG before. The phone has a solid body, good ergonomics and looks like a premium device. A hopeful option that I really liked.
Characteristics LG G2 D802 32
The display is one of the areas that LG has focused on, and the G2 is a prime example of this. The Full HD IPS screen is incredibly bright and readable in good sunlight, displaying deep colors, but not as oversaturated as AMOLED panels. It rivals the SLCD 3 screen on the HTC One or Apple iPhone 5. Above and below the display is framed by a narrow bezel, which is almost invisible on the sides, creating the illusion of a solid screen.
Slightly modified Optimus user interface
In terms of software, the phone has Jelly Bean 4.2.2 installed along with the interface. The interface uses all the old Optimus G Pro tricks, as well as some new ones.
The G2 is powered by the most powerful Snapdragon processor 800 SoC from Qualcomm with 2.2 GHz and 2 GB of RAM. Despite its speed, the G2 never overheats, even after using the camera, GPS or gaming. Rear panel it can get barely warm, but nothing more, and this is certainly impressive.
Damn fast
Multimedia LG G2 D802 32
The audio and video players in the G2 have been modified in different ways and one of the major enhancements is support for 24-bit 192 kHz audio, which matches studio quality. This will support the playback of audio files in FLAC format, and the difference between it and MP3 format is quite noticeable, especially through headphones. The sound from the speaker is quite loud. The phone comes in two versions - 16 GB and 32 GB, but, unfortunately, in both it is not clear why there is no slot for expanding memory. The G2 is clearly wide enough on the sides to accommodate a microSD card slot, and you could have left the connector as in previous LG models. We continue review LG G2 D802 32 GB .
Very good reproduction media files
The video player plays most video formats including MKV. New: Added Audio Zoom, which allows you to selectively listen to audio from a video recording, muffling everything else. The problem is that for it to work, you need to use digital zoom, which reduces the quality of the video. Whatever I did, the effect was not very convincing.
Connectivity
D802 model supports LTE but not TDD-LTE. However, there is a variant G2 (D802TA) that supports TDD-LT. In addition to the available 4-frequency 3G band, there is built-in Wi-Fi ac, Bluetooth, NFC, Miracast, GLONASS, IR and TV-out via MHL. The quality is very good and the speaker sound is quite loud, audible even in noisy environments.
There are both useful and unnecessary functions
The wireless connection is a very convenient addition that allows you to access your phone wirelessly through your laptop. Provided you have an appropriate network, you just need to enter the IP address of your phone and you can view and edit your files without the need for a physical (wired) connection.
Cameras in LG G2 D802 32GB
The G2 boasts the first 13MP sensor for Optical Image Stabilization (OIS). This feature is similar to what was on the Lumia 920, stabilization works well with minor hand shake, but not so well when it comes to recording from a moving vehicle. But still, in this area, it can not be compared with Nokia. The camera performs well in good lighting conditions. The level of detail is just as good in macros; We noticed that post-processing created unwanted effects around the edges that were only noticeable at any magnification. The same thing happens when shooting landscapes, detail remote objects not as clear as it should be. I think a software update should fix this. Night shots are thankfully not as bad as the Z1, as no color distortion is noticeable in dark areas.
Good macros, but detail around the edges of the flower is not very high when viewed at a larger scale
Landscape shots are good, but again, there is no detail in distant subjects
Video recording is excellent, with a resolution of up to 1080p at 60 frames per second. In addition to double recording, there is also a live effect that transforms the photographed faces and adjusts the zoom when recording video with overlay windows.
Battery capacity
The 3000 mAh battery is excellent, the G2 easily lasts for two whole days of continuous use. After an 8 hour test cycle for writing Review LG G2 D802 32GB , there is still about 43% of the battery remaining.
Conclusions on LG G2 D802 32GB
The 16GB G2 version costs only slightly less than the 32GB version. Of course, you can find them online for less, making the G2 one of the most money-saving flagships on the market. The inability to increase memory is perhaps the only major drawback of this phone. It has a very pleasant appearance, it has lightning speed, it has a great screen, and there are even more actions and functions than necessary, plus a very capacious battery. Choosing between it and the Sony Xperia Z1, I would go for the G2.

The LG G2 smartphone has a number of unique features, runs on the new Qualcomm Snapdragon 800 hardware platform, has a 13 MP camera with optical stabilization and the ability to record Full HD video at 60 frames per second, while its cost is lower than that of its closest competitors. Is this enough to become the best and win users' sympathy? We have been looking for the answer to this question for a long time.
Equipment
Hardware platform
Today, the LG G2 is the first public smartphone based on the Qualcomm Snapdragon 800 SoC. The Qualcomm Snapdragon 800 system-on-a-chip is manufactured using a 28nm process technology and includes four Krait 400 processor cores running at 2.26 GHz, graphics core Adreno 330 @ 450MHz with OpenGL ES 3.0 support plus 2GB dual channel memory LP-DDR3 (800 MHz). The availability of Qualcomm Snapdragon 800 also implies support for LTE networks. System-on-a-chip capabilities allow you to record 1080p video at 60fps or 2160p (4K video) at 30fps. LG decided to stick with the first option, despite the fact that at the annual IFA 2013 the company unveiled many 4K TVs.
Since with playback standard set LG G2 copes with video files effortlessly, we made it a little more difficult for him by replacing SD-clips with files with Full HD-resolution with high bitrate and increased frame rate. In the future, this particular set of files will be used in all test devices. By the way, all the videos were also swallowed by the smartphone without the slightest effort. This means that when downloading a video to a smartphone, the user does not have to worry about video and sound formats, video resolution, bit rate and frame rate, LG G2 can handle anything. Playback can be accompanied by titles (size, style, background, its transparency and text color are adjustable). The video is played in full screen or in a separate window (QSlide), and while watching Full HD video at 60 fps, you can launch HD video on YouTube, this will not slow down the device at all, while the sound will be output from two sources simultaneously ...

The sound volume in the headphones is above average, but the volume of the multimedia speaker is not enough in all situations. Perhaps this is a consequence of the reluctance of the developers to bring the speaker to a rattling sound when listening to music at high volume.
According to the results of popular benchmarks, the LG G2 smartphone takes the first lines among all devices available today. Recall that by default, all LG smartphones have a performance limitation associated with overheating of the processor.
The search for GPS satellites occurs in a matter of seconds, during which the smartphone has time to detect about 20 satellites. The data transfer rate in the WiFi network is as close to possible (the test router supports the b / g / n standards). The data transfer rate on the mobile network is also fast.
The music player remained practically unchanged, they added the ability to play music from external devices connected by the same wireless network or from cloud services... Another addition is YouTube search for the song being played. That is, in one click, the user can find a video for the melody that interests him.
One of the most important questions for the LG G2 is its autonomy. To find out this parameters, we used the Antutu Tester application and conducted two-hour tests. Antutu's scores were unexpectedly among the lowest. Perhaps this is due to the fact that an engineering sample was tested, a commercial one was not yet available at that time, or the fact is that the device had to travel around the city in a bag, therefore, it remained for a while without WiFi and was not able to cool. Once we run a similar test on a commercial sample, we will update Antutu results Tester. When it comes to the two-hour benchmarks, with the exception of two of them, YouTube videos and music playback, the LG G2 performed record-breaking. In part, the smartphone owes these results to the new processor, but there is another trick - GRAM - graphics memory that saves 26% of the battery charge when displaying static images.

To listen to music, we used a standard player, volume at 12 out of 15 possible, MP3 files with a bitrate of 320 Kbps. In read mode, all wireless communications are disabled, including data transmission in the mobile network, and the display brightness is set to 50%. Navigation includes laying a route in google app Navigation. Brightness is set to 50%, all communication modules are disabled. During video playback, the display brightness is set to 50%, the sound volume in the headphones is at level 12 out of a possible 15. The video file format is MKV, the resolution is 1024x432 pixels, the frame rate is 24. When playing a video from Youtube, the display brightness is set to 50%, the sound volume in the headphones is set to 12 out of 15 possible levels.
The table shows that the LG G2 is not only slightly better than its closest opponents with Full HD screens, some results are twice as good. For example, in two hours of reading, LG Optimus G Pro consumes 24% of the battery charge. LG G2 for the same time, in exactly the same conditions, is content with 11%. Theoretically, the battery life of a smartphone when used as a reader is 18 hours.
To tell about how long the smartphone will work with a typical usage pattern - several hours of reading social networks a day, automatic sync two accounting Google records, test messages, a few minutes of telephone conversations, while it is difficult. But what is known for sure is that in exactly the same scenario, plus several dozen photographs and performance tests, the smartphone was discharged from 100% to 35% (this includes 2 hours of navigation in Google maps and 2 hours of reading in FBReader) in one day. At the same time, the operating time of the screen was 6 hours and 32 minutes - this is a very good indicator. From 15% to 100%, the battery is charged in exactly two hours.
Display
LG has several factories that produce matrices for TVs, monitors and mobile phones. Therefore, there is nothing surprising in the fact that even inexpensive smartphone models are equipped with IPS-matrices. As well as it is not surprising that the LG G2 received one of the best developments in this area. The smartphone display has a diagonal of 5.2-inches, a resolution of 1920 x 1080 pixels (424 PPI) and is made using ZeroGap technology - that is, there is no air gap between the sensor and the matrix. To create minimal frames on the sides of the screen, I had to develop new type sensors, he received two controllers, while the rest of the devices use one. The display is covered with tempered glass Corning Gorilla Glass 2 with an oleophobic coating. In addition, an anti-glare layer is used, the work of which is clearly visible when exposed to direct sunlight. Without it, the LG G2's display would be unsuitable for outdoor use, as the maximum brightness is a modest 349.5 cd / m². The minimum is 6.3 cd / m² and the average is 44.5 cd / m². Automatic brightness control works in the same way as other LG smartphones. By setting the slider to the extreme left or right position, the brightness will always remain minimum or maximum, while moving it to the middle allows you to change its intensity to a relatively comfortable level in dim and office lighting. To make the smartphone comfortable to use on the street, the slider has to be moved beyond a value of 70% and higher.
The factory calibration of the display is commendable. The temperature almost over the entire segment is 7000K, the gamma curve is also relatively linear and close to the value of 2.22 - this means that dark and light colors are displayed correctly. As for the naturalness of color reproduction, then everything is fine here, and only green is slightly oversaturated, which, however, does not go beyond the permissible limits.
Camera
The LG G2 is the first device to feature a 13MP camera with OIS. The front camera has a 2 MP sensor. Both cameras shoot Full HD-video, with the only difference that the main one does it with a frequency of 30 or 60 frames / s. The difference between 30 and 60 fps is visible to the naked eye. Another feature of the LG G2 is nine-point focusing, a first for smartphones. To call the camera from sleep mode, just press and hold the volume down key. When you exit the camera, all selected settings are saved.
The viewfinder has remained almost the same as in previous models, changes have been made to the settings and the choice of shooting modes. Still, to record a video or photo, you need to move the slider in the desired direction, while most manufacturers have long added separate keys for shooting and recording video. On the left side of the screen there are shortcuts for selecting the flash mode, switching to the front camera, shooting mode and calling up settings. Shooting modes contain 12 presets. To find out which mode, for which conditions it is intended, it is enough to switch to vertical display list. In this case, a detailed explanation will be displayed to the left of the modes.
From the unusual, we also note the possibility of manual focusing. It is useful in cases when you need to take several frames from the same distance, for example, photographs of the same object with different ISO values.
"Smart auto-mode" 
Manual focus, ISO200 Despite all the improvements and changes, there are two complaints about the camera. The first concerns not the fastest focusing. The second is the blurring of photos when shooting in low light. It will be possible to pass a verdict after a comparative test of the cameras. In the near future, we will be comparing the camera of the LG G2 and the Samsung Galaxy Note 3. In the meantime, one thing can be said, the LG G2 received good camera, it allows you to compete on equal terms with the best of the current year.

Outcomes
The LG G2 is unique in many ways. For example, this is the first smartphone equipped with a 13 MP camera with OIS. It is also the first in which mechanical control keys are combined into a single unit located on the back of the case, and this was done not so much to stand out, but because of the research results that showed that such a key placement is the most optimal. Indeed, in order to reach the power / lock or volume keys, the user does not have to intercept the smartphone, in most cases your index finger is already on them. Moreover, the very presence of the lock button is quite symbolic, since double tapping on the screen can be used to unlock and lock the smartphone, and the absence of a dedicated camera key is compensated by the ability to start it by holding down the mechanical key responsible for decreasing the volume. All this is done in order to minimize the inconvenience associated with the transition to a smartphone with a large diagonal screen.
Of the pleasant features of the LG G2, which make it one of the most interesting new products of the fall, we note thin bezels around the screen, the Qualcomm Snapdragon 800 hardware platform, excellent battery life, support for all currently available wireless communication modules and high quality sound in headphones.
The LG G2's closest competitor is the Samsung Galaxy S4. It is also equipped with a Full HD screen of a comparable diagonal, a 13 MP camera, an up-to-date hardware platform, has many additional accessories and is sold at a comparable price. On the side there is a slot for memory cards. Another smartphone that can compete with the LG G2 -. It is equipped with stereo speakers delivering loud and high-quality sound, a Full HD-screen, albeit a noticeably smaller diagonal, a camera with optical stabilization, but again, with a significantly lower resolution and, for some, this is an important advantage, it has a metal body. The price of these three smartphones is comparable, but the LG G2, despite the fact that it is just appearing on store shelves, turned out to be the most affordable of them.

Screen
LG has equipped its G2 with a stunning Full HD screen, made by IPS technology, measuring 5.2 inches. The screen is covered from above with a protective Gorilla Glass 3, resistant to scratches. Moreover, the screen here occupies almost the entire area of the front surface: the frames around the screen, as mentioned earlier, are so thin that sometimes you get the impression of their complete absence - as if you are holding only the display in your hand. In numbers, the physical parameters of the smartphone screen are as follows: dimensions - 65 × 115 mm, diagonal - 132 mm (5.2 inches), resolution - Full HD 1080p (1920 × 1080 pixels), pixel density is 423 ppi - very good, although not a record figure.
The brightness of the display has both manual and automatic adjustment, the latter is based on the operation of the light sensor. Multi-touch technology allows you to simultaneously process up to ten touches, which is confirmed by tests. There is also a proximity sensor that locks the screen when you bring the smartphone to your ear. In addition, the LG G2 is equipped with graphic random access memory (GRAM), which is used to update the screen (the screen buffer is placed in it, which allows you not to "jerk" the RAM unnecessarily). According to the developers, the GRAM memory reduces the power consumption of the screen by up to 26% when displaying a still image, which generally increases the time autonomous use smartphone by about 10%.

Alexey Kudryavtsev, editor of the "Monitors" and "Projectors and TV" sections, carried out a detailed examination using measuring instruments. Here is his expert opinion on the screen of the tested sample.
The smartphone screen is covered with a glass plate with a mirror-smooth surface and, judging by the reflection of bright light sources in it, it has a very effective anti-glare filter, surpassing the Google Nexus 7 screen filter in terms of reducing the reflection brightness. The doubling of reflected objects is to some extent present, but the shadows of the objects are very faint, which indicates that there is no air gap between the outer glass and the matrix surface. On the outer surface of the screen there is a special oleophobic (grease-repellent) coating (very good, better than that of Google nexus 7), so fingerprints do not appear as quickly as in the case of ordinary glass, but are removed more easily.
With manual brightness control, its maximum value was 500 cd / m², minimum - 7 cd / m². As a result, at maximum brightness with a bright daylight the smartphone can be used without much inconvenience, and minimum brightness will allow you to comfortably work with this mobile device even in complete darkness. There is an automatic brightness control by the light sensor (apparently, it is located to the right of front camera). This function depends on the position of the brightness adjustment slider. If it is set to 100% or 0%, then the screen brightness does not change (it always remains equal to 500 cd / m² and 7 cd / m², respectively); if by 50%, then in complete darkness, the auto-brightness function reduces the brightness to at least 17 cd / m2 (you can still read from the screen), in an office illuminated with artificial light, it sets to 100 cd / m2 (acceptable), in a very bright environment it increases to maximum 500 cd / m². Obviously, the ranges of automatic adjustment were not chosen very well, since there is no adjustment at the extreme values. However, the position of the slider by 50% provides a fairly adequate operation of this function. At low brightness, there is virtually no backlight modulation, so there is no screen flickering.
This smartphone has an IPS-type matrix. The micrograph shows a typical IPS subpixel structure:
The subpixels seem to consist of two halves, which is quite unusual, since, for example, even in HTC One, which has a higher pixel density, you can see 4 parallel "beds" in each subpixel. Dark areas between the subpixels, arranged in an orderly manner, may indicate that a capacitive touch sensor is integrated into the matrix.
The screen has good viewing angles - no tint inversion and no significant color shift up to reasonable perpendicular viewing angles to the screen. When looking almost parallel to the screen, the darkest shades are inverted, but this can already be attributed to the distinguishing features of the matrix, and not to the disadvantages. The black field is strongly lightened when deviated along the diagonal, but remains close to neutral gray. When viewed from a perpendicular view, the uniformity of the black field is good. The contrast is high - about 1300: 1. The gamma curve plotted at 32 points did not reveal any blockage in highlights or shadows, and the exponent of the approximating power function is 2.34, which is slightly more than the standard value of 2.2, while the real gamma curve slightly deviates from the power law:
Due to the dynamic adjustment (not very pronounced) of the backlight brightness in accordance with the nature of the displayed image, the obtained dependence of brightness on the hue (gamma curve) may slightly not correspond to the gamma curve of a static image, since the measurements were carried out with sequential output of shades of gray on the entire screen ...
Response time for black-white-black transition is 24 ms (13 ms on + 11 ms off), transitions between semitones gray 25% and 75% (based on the numerical value of the color) takes 36 ms in total.
The color gamut is actually sRGB:
The spectra show that the matrix filters moderately mix the components together - as a result, the colors on this screen are close to natural in saturation.
The balance of shades on the gray scale is good, since the color temperature is slightly higher than the standard 6500 K and its variation is small, and the deviation from the spectrum of a completely black body (delta E) is significantly less than 10, which is considered a good indicator for a consumer device, and also changes little from hue to the shade. (The dark areas of the gray scale can be ignored, since the color balance there is not very important, and the error in measuring color characteristics at low brightness is large.)
A significant drawback of this screen is the low stability of the black color when the gaze is deviated from the diagonal. There are no complaints about other important characteristics - excellent anti-glare filter and oleophobic coating, high brightness and contrast, sRGB coverage, close to standard color balance.
Camera
LG G2 is equipped, like most modern smartphones, with two modules digital cameras... The main rear 13-megapixel camera is equipped with an optical stabilization (OIS) and multi-point autofocus (Multi Points AF) - these functions are especially highlighted by the developers when describing the new camera. It is also noted that the camera optics are covered with a protective sapphire glass.
By default, the camera shoots in normal mode with a wide aspect ratio of 16: 9, the images are 4160 × 2340 (10 megapixel). In order to achieve the maximum resolution, you must manually switch the settings to the aspect ratio of 4: 3, then the pictures will be obtained with a resolution of 4160 × 3120 (13 megapixels). Examples of photos taken in automatic mode "out of the box", as well as at maximum resolution, are shown below with comments.

The tree has worked well, but the foliage merges in places. On buildings on the edges, not very neatly suppressed noises are felt. Sharpness drops slightly towards the left edge. |
 |
There is still a drop in sharpness on the left edge. In general, the sharpness of the picture is not bad - we can distinguish the number of a car that is not the closest one. |
 |
Decent sharpness in the distant shots. |
 |
In general, sharpness is good, if you do not look at the left edge of the frame. |
 |
Sharpness is good. A strong highlight of the sky is caused by spot metering. |
 |
Not a bad result in low light conditions. The noise is almost imperceptible. |

Not the worst macro, but nothing outstanding. |
Below are photos taken with the 13-megapixel cameras of the LG Optimus G and LG G2 for comparison.
Photos taken with the LG Optimus G camera:
The LG G2's camera is a noticeable step up from the LG Optimus G's camera, which was also pretty good. At lower ISO values and at slower shutter speeds, the LG G2 does a much better job.

For some reason, the G2 program diligently overwrites the EXIF of pictures taken in the dark. Either LG is hiding some "know-how", or they do not want to frighten us with huge values of light sensitivity. It is worth noting that the noise in such images is simply awful, but, nevertheless, it will be possible to get some idea of the subject.
The G2 flash, although better than the Optimus G flash, is still weak and does not allow you to get the original resolution.
As you can see from the graphs, according to the results of the laboratory test, the LG G2 camera is still the first in "laboratory" sharpness compared to cameras of other smartphones. This, of course, is a significant indicator, but perhaps it does not characterize the camera as a whole. Nevertheless, the G2 camera is made very worthy, and in the field does not do much worse than in the laboratory. The stabilization system deserves special attention, which allows the camera to use long exposures without affecting the image.
It feels like smartphone camera makers are on the right track and are getting close enough to the quality of compact cameras. There are still many parameters that do not allow them to equalize, but the noise reduction options offered by the manufacturers of the latest smartphone models cannot but command respect.
The LG G2's video camera shoots in Full HD 1080p at 30fps by default, but there is also a 60fps shooting mode in the settings. For comparison, below are videos shot in both modes. Clips are saved in an MP4 container (video - MPEG-4 AVC [email protected]/4.2, audio - AAC LC, 156 Kbps, 48 kHz, 2 channels).
- Movie # 1 (52.3 MB, 1920 × 1080, 30 fps)
- Movie # 2 (82.3 MB, 1920 × 1080, 60 fps)
In addition to the normal shooting mode, software LG G2 cameras have other modes that allow you to add extraordinary elements to the familiar picture. For example, in the "Live Effect" mode, you can distort the hero's face with a small mouth, a large nose, etc. The "Dual Record" mode allows you to display in a separate window over the main picture what is filmed with the front camera (mostly it turns out to be the owner's own face of the smartphone focused on the shooting process). Last mode called "Tracking Zoom" and produces a picture similar in composition, only here in a separate window, superimposed on top of the usual video sequence, the area on which the crosshair is focused will be displayed on an enlarged scale. In the process of filming this window with a "lens" magnifying the image, you can move your finger across the entire screen from object to object. An example of such a video is shown below.
- Movie # 3 (17.6 MB, 1280 × 720, "Tracking zoom")
There are even more different modes for taking pictures. Here, in addition to the usual night, sports, panoramic, there are also burst shooting, and the same shooting mode simultaneously for the rear and front cameras, and even such an option when, after taking a picture, the camera itself highlights with a dotted line the places that, in its opinion, do not correspond to the general picture and immediately suggests erasing them on the spot. We cannot fail to mention the Audio Zoom mode, in which you can increase the volume emanating from a specific selected object in the shooting field. There are many modes, those who like to delve into the settings here have a lot to turn around. Shooting can be done either by touching the screen or by pressing any of the volume keys located on the back of the smartphone.
Performance
The hardware platform of the LG G2 is based on the Qualcomm Snapdragon 800 SoC. The central processor here has 4 Krait 400 cores, clocked at 2.2 GHz (CPU-Z shows 2.27 GHz). The processor is supported in graphics processing by the most modern video accelerator Adreno 330. The device provides 2 GB of RAM, and the storage available to the user to upload their own files is just under 25 GB out of the nominally designated 32 GB. The device does not support memory cards, but it is possible to connect external media using OTG (USB host) mode. By the way, when a USB device is connected, the Plug & Pop function mentioned in the first part of the review is immediately triggered, displaying a strip with a selection of applications that are most associated with the situation on the screen. In the standard composition, the strip contains icons for music and video players, photo galleries, as well as the built-in file manager itself, but, of course, you can bring any others here and fix them to open by default.

All the results obtained by us when testing the LG G2 smartphone in the most recent versions of popular benchmarks, we have summarized for convenience in tables. For comparison, only those models of top-end smartphones have been added that have managed to pass tests on similar, most current versions of programs. Unfortunately, within the framework of one comparison, it is impossible to present the results from different versions benchmarks, so many worthy and up-to-date models had to be left behind the scenes - due to the fact that they once passed their “obstacle courses” on old versions of test programs. Details below.
As for testing the graphics subsystem in the 3DMark cross-platform test, the subject "flew" out of the maximum possible result, which is why he got the mark "Maxed out!" For the most productive smartphones, it is now possible to run 3DMark in Unlimited mode, where the rendering resolution is fixed at 720p and VSync is disabled (which can cause the speed to rise above 60 fps). Thus, when testing flagships, one should look at 3DMark Ice Storm Extreme and 3DMark Ice Storm Unlimited.
In the Epic Citadel gaming test in High Performance mode, the LG G2 achieved an excellent 56.7 fps result. True, in this mode, almost all modern GPUs in mobile SoCs, but the LG G2 does not sag in the tougher High Quality / Ultra High Quality modes (56.3 and 51.3 fps, respectively). In contrast, by the way, from the same Samsung Galaxy Note3, which beat all records with a low scene complexity, and "blown away" on the test in Ultra mode. Details in the table.

As for the benchmarks for evaluating the speed of the javascript engine, the results in them significantly depend on the browser in which they are launched, so that the comparison can be correct only on the same OS and browsers, and this possibility is not always available during testing.
Video playback
To test the "omnivorous" video playback (including support for various codecs, containers and special features, such as subtitles), we used the most common formats, which make up the bulk of the content available on the Web. Note that it is important for mobile devices to have support for hardware decoding of video clips at the chip level, since it is often impossible to process modern versions at the expense of processor cores alone. Also, do not expect a mobile device to decode everything, since the leadership in flexibility belongs to the PC, and no one is going to challenge it. All results are summarized in a single table.
Since the Micro-USB connector here supports USB-host (OTG) mode, a device with such a large and high-quality screen can comfortably be used as a multimedia combine. It is enough to connect any flash drive through the adapter, and you can play music, movies, view photos directly from it, especially since the developers initially supplied the device with all the necessary decoders. A smartphone out of the box is able to play most of the common file types out of the box, and due to this, it is one of the best solutions for multimedia needs on the mobile market.

This smartphone says: "HDMI connector is available", but, of course, there is no HDMI connector, there is support for SlimPort (or Mobility DisplayPort) adapters connected to the Micro-USB connector and providing video signal (and sound) transmission to external devices display. This time we already had a SlimPort to HDMI port adapter. For testing, we used an LG IPS237L monitor. Output with this monitor and adapter was 1920 x 1080 pixels @ 60 fps. When the smartphone is in landscape orientation, the image is displayed on the monitor screen in landscape orientation, while the image on the monitor is inscribed in the boundaries of the screen and is an exact copy of the smartphone screen. In the portrait orientation of the smartphone, everything that can be rotated to landscape orientation is displayed in the same way, in other cases (for example, start screen) the display of the image on the monitor screen may be carried out in portrait orientation, but we have not verified this.
Sound via HDMI is output (in this case, the sounds were heard through the headphones connected to the monitor, since there are no speakers in the monitor itself) and is of good quality. At the same time, multimedia sounds are not output through the loudspeaker of the smartphone itself, and the volume is controlled by buttons on the smartphone body. The smartphone connected to the SlimPort adapter is being charged, and the adapter must be connected to a power source through its existing Micro-USB connector.
The video output by means of a standard player deserves a special description. To begin with, using a set of test files with an arrow and a rectangle moving one division per frame (see Methodology for testing video playback and display devices. Version 1), we checked how the video is displayed on the screen of the smartphone itself. Screenshots with 1 s exposure helped determine the frame output of video files with different parameters: the resolution varied (3840 by 2160 (4K), 1280 by 720 (720p) and 1920 by 1080 (1080p) pixels) and the frame rate (24, 25, 30, 50 and 60 fps). The results of this (block titled as " Screen") And subsequent tests are summarized in the table:

Note: if both the "Uniformity" and "Gaps" columns have "green" ratings, this means that when watching movies, most likely, either artifacts caused by uneven alternation and skipping of frames will not be visible at all, or their number and visibility will not affect the viewing experience. "Red" marks indicate possible problems related to the playback of the corresponding files.
According to the criterion for outputting frames, the quality of video playback on the screen of the smartphone itself is high, since frames (or groups of frames) are displayed with a more or less uniform alternation of intervals and frame drops or not, or single frames are skipped. However, the uniform interleaving of frames is a relatively unstable state, since some external and internal background processes lead to periodic failure of the correct interleaving of intervals between frames and even to the skipping of individual frames. When playing video files with a resolution of 1920 by 1080 (1080p) on a smartphone screen, the image of the video file itself is displayed exactly to the width of the screen, one to one pixel by pixel, that is, in the original resolution. The brightness range displayed on the screen corresponds to the standard range of 16-235 - all shades are displayed in shadows and highlights. The smartphone can even display 4k files - though up to and including 24p.
With a monitor connected via SlimPort, during video playback with a standard player, the video file is displayed only in landscape orientation, while only the video file is displayed on the monitor, and only information elements and virtual controls are displayed on the smartphone screen:
When playing video files with a resolution of Full HD (1920 x 1080 pixels) on the monitor screen, the image of the video file itself is displayed exactly along the edge of the screen, maintaining the true proportions, and the resolution corresponds to the Full HD resolution. The brightness range displayed on the monitor is equal to the standard range of 16-235, that is, in the shadows and highlights, all gradations of shades are displayed. The results of the tests on the monitor are shown in the table above in the block “ SlimPort". Output quality is good, but not perfect.
It turns out that the SlimPort connection to external monitors, TVs and projectors can be used to play games, watch movies, display web pages, and other activities that benefit from the exponential increase in screen size. Note that for the first time we were able to observe the output of a Full HD signal (with a resolution of 1920 by 1080 pixels) in a progressive format with a frequency of 60 fps via a Micro-USB connector. Formally, the devices with MHL support and the corresponding adapters that visited us for testing were supposed to work with the same quality, but in practice, for some reason, this did not happen.
Battery life
The LG G2 has a 3,000mAh lithium-ion battery. The battery is non-removable, so if the battery is swollen or otherwise damaged, you won't be able to replace it with a new one yourself, and you can't buy a spare one.
Testing in standard user modes of use, the LG G2 has shown excellent battery life. LG representatives tirelessly repeat that they have developed a unique battery for themselves (and LG factories are capable of this, because the company once started with a chemical production), and here are the results confirming this. The LG G2 smartphone with a huge bright screen shows the results of battery life twice as high as those that were considered the norm in the camp of smartphones last year. In fairness, it should be noted that the Samsung Galaxy Note3 also produces record figures, although in game mode, like the Galaxy S4, it sags, overheating. (Exactly the same picture was observed on the Samsung Galaxy S4 until it was released new firmware- then everything immediately fell into place. Apparently, the same is waiting for the Galaxy Note3.)
Continuous reading in the FBReader program (with a standard, light theme) at a minimum comfortable brightness level (the brightness was set to 100 cd / m2) lasted 20 hours until the battery was fully discharged, and for continuous viewing of YouTube videos in high quality (HQ) The device spent 12.5 hours with the same brightness level through the home Wi-Fi network. In game mode, the smartphone lasted almost 4 hours and 45 minutes, which is not an ordinary figure, especially considering the size and resolution of the screen.
Outcome
As for the price, it has already been determined and is now 25 thousand rubles in our market. This price is fully justified (if, of course, an appropriate correction is made for the distorted realities of the domestic market). The smartphone really turned out to be extremely remarkable: maximum performance, coupled with a record battery life, plus an excellent screen in all respects, which, moreover, fits into very digestible dimensions - all this is LG G2. You can find fault, perhaps, only with the design: the convenience of the control elements located on the back wall is still a big question, and the design itself in the form of a brand of glossy boat has already blurred the eye. Otherwise, there are no complaints about the device, and the award from the editorial board for a perfectly balanced product will be very useful here.
Despite the successes of the Korean company LG Electronics in the segment of household appliances, its mobile division was practically outsiders, playing mainly the role of catching up and releasing at the same time insufficiently balanced and ill-conceived devices, some of which were either ahead of their time - which is why they did not use popularity, or, simply, suffered from flaws in the assembly, quality of work, support, etc.
Nevertheless, LG still managed from time to time to grope for that so important thread necessary to create really interesting models that were in good demand and support from both the manufacturer and the Internet community, which released alternative firmware versions based on CyanogenMod. The turning point in the manufacturer's activity was 2012, which brought with it the popular series inexpensive models the LG L line, already updated to the second generation, and provided the unprecedented model of the year - the LG Nexus 4, created in cooperation with by Google, and then - re-released in the form of its own, no less good flagship model LG Optimus G.
In fact, it is the G-series models that have lost the Optimus prefix this year that have become the main calling card of LG. This year, this line has been replenished with several more interesting devices, including the innovative hit of the season - LG G2, with the features of which we will understand in the continuation of the material.

Delivery and packaging
The smartphone is packed in a small box made of very thick cardboard, which protects the device located inside well enough during transportation. It is painted white, and the visual design, which, in general, is not, can only offer a couple of logos: "LG" and "G2". In addition, on its back there is quite extensive information about the main characteristics and supported functions, as well as about certification marks, among which there is UA UCRF. Technical information about the delivery, including: a list of supported frequencies in 2G, 3G and 4G networks, model name, body color, production date and IMEI number - is located on the front sidewall.
We received a pre-sale version of LG G2 for testing, the package of which included only a user manual, a special “G”-shaped paper clip to access the SIM-card tray, and two protective films on the front and back sides. The retail version will also offer a small charger with a detachable USB ↔ micro-USB cable. Headphones and other accessories will have to be purchased separately.
Appearance, design
In general, the design of the LG G2 is not much different from many touch monoblocks both LG itself and almost any other manufacturers who like to use black in combination with the ubiquitous gloss, and do the general outlines with a tangible rounded corners and faces. Be that as it may, the smartphone looks nice, and it would be stupid to deny it, especially since a close acquaintance with the model reveals several interesting and sometimes insignificant details, trying with all their might to distinguish the device from the general mass.
For example, a thin chrome strip runs along the perimeter of the case, which, although it is only decorated plastic, creates the impression of the presence of metal in the structure. Moreover, this is partly true, because a solid magnesium frame is used inside the smartphone. By the way, chrome, only in an even thinner version, is also present on the rim along the contour of the front panel.
In addition, the back side of LG G2 looks interesting, which in this model is not just glossy. There is a slightly “sparkling” diagonal pattern under the cover, very much like a fabric. At the same time, the plastic itself is slightly textured and allows you, as it were, to feel the structure of the material (this is especially noticeable if you hold it with your fingernail).
The front side of the smartphone with rounded edges in the manner of the fourth "nexus" is covered with a protective glass Corning Gorilla Glass 2 and boasts a huge 5.2-inch display and record small frames, which is twice impressive. Of course, it is still not possible to completely get rid of them, but, apparently, it will not be long to wait for completely frameless smartphones. In LG G2, the distance from the display to the side edge is only 2.65 mm, but in real conditions it seems much less. The thickness of the upper and lower frames is also small - 9 and 12 mm, respectively.
The manufacturer emphasizes that such results were achieved thanks to an innovative solution for mobile devices. Dual technology Routing, which implies the use of two connectors at once for connecting a sensor substrate, and not one, as in all other smartphones.
The overall dimensions of the LG G2 are quite small and only slightly exceed those of the Samsung Galaxy S4 and HTC One (138.5 x 70.9 x 8.9 mm versus 136.6 x 69.8 x 7.9 mm and 137.4 x 68.2 x 9.3 mm respectively). At the same time, these smartphones are equipped with noticeably smaller displays - 5 and 4.7 inches, respectively. It is quite convenient to operate a smartphone with one hand, but it takes a little getting used to. As for the weight, it is equal to 143 grams, which, in our opinion, is the optimal value for a device of this class.
As mentioned, the outside of the smartphone is made of plastic and glass, while the inside is complemented by a magnesium frame. The build quality is definitely very good, but there is still one gripe. It concerns the presence of an extremely small gap between the protective glass and the side frame, where dust begins to clog over time. The LG G2 has a non-separable body, which makes it possible to get to the battery only through a service center. But it is tactilely perceived by a tightly knocked down monolith and is distinguished by enviable rigidity: when trying to pressure and twist, characteristic sounds appear only when very strong impact which is difficult to achieve in real conditions. Doubts about the strength of the novelty can only be caused by the slightly rattling focusing lens of the main camera, which, however, is just a feature of the module's structure.
The LG G2 is only available in two color options: black, which actually looks more like a deep blue with a gray tint, and snow white. However, for fans of bright colors, the branded cases of LG G2 QuickWindow are perfect, available in black, white, red-pink, blue, purple, yellow and turquoise.
Arrangement of elements
The upper part of the front side contains a rather wide slot conversational dynamics, decorated with a fluted metal trim and a fine-grained mesh above the speaker itself. It looks nice, but the practicality is somewhat disappointing, since it is constantly necessary to blow out the accumulating dust. To the left of the slot are located: light and proximity sensors, a notification indicator that glows in several colors depending on the situation, as well as a front camera.
At the bottom there is only a chrome logo of the manufacturer, which is a little distracting. The touch buttons that were in the LG Optimus G are not. They are presented on-screen.
The back side from above is occupied by: the main camera module, covered with a sapphire crystal, an LED flash and three control buttons, which we will discuss in more detail below. In addition, there is another chrome logo of the LG company, and under it are applied: the name of the device model, country of production and certification marks.
On the left side there is only a tray for installing a SIM card and a hole for removing it using the supplied G-clip (or any other sharp and thin object). The right side remained completely empty.
The bottom side contains: a micro-USB 2.0 connector, a headphone jack (mini-jack 3.5 mm) and two perforated grilles, under which, it would seem, should be located stereo speakers. But no, there is only one speaker and it is hidden under the right grill, while the main microphone is located under the left one. Above, there is a second microphone and an infrared port, with which you can easily control any modern technology that has a remote control.
Rear Key
The most unusual and, at first glance, extremely inconvenient feature of the LG G2 is the rejection of any side controls and their transfer to the central part of the "back", exactly under the camera module, which, in turn, caused a lot of controversy. However, in fact, such an arrangement, which received the brand name Rear Key, turns out to be inconvenient, or rather unusual, only during the first hours of using the smartphone. Oddly enough, but it is on this or an adjacent place that the index finger rests during a conversation, allowing you to quickly adjust the volume. The use of such a design, as the manufacturer notes, made it possible to fit a more capacious battery into the device, which is rather controversial, because it mainly occupies lower part internal volume. But, thanks to the resulting symmetry of the case, LG G2 fits equally comfortably in both the right and left hands.
In total, there are three familiar buttons, namely: a wide volume rocker with an inscribed (slightly convex) power / lock button in the center. The latter is chrome-plated and features a contoured LED notification indicator, and small tabs are provided on either side of it for more convenient search buttons, for example, when the smartphone is in your pocket. In addition, this protrusion slightly raises the upper part of the body, thereby ensuring less contact. protective glass cameras with surfaces.
The rocker, in addition to the basic function, has several additional ones. So, a long press on the volume up button calls up Quick app Memo that lets you create quick handwritten notes. Holding the volume down button launches the camera, in which these buttons can be used to take pictures or zoom (the mode of operation changes in the application itself). But it is impossible to assign any other function, but such a possibility, in all likelihood, should appear in the upcoming update of the operating system.
As for the process of unlocking a smartphone using the rear button, there are several nuances here, because the search for this very button is not in all cases convenient and can lead to irreversible consequences. For example, in the case when the LG G2 is attached to the dashboard of a car and is used as a navigator. Therefore, so that every time they do not reach for the unlock button and not tempt fate, the smartphone provides an alternative, faster and more convenient way - KnockON - double tap anywhere on the screen to unlock and double tap on an empty spot on the desktop or on the notification bar to reverse lock. At the same time, you don't have to worry about accidental unlocking. this process is directly related to the proximity sensor. In other words, if the sensor detects an obstacle in front of it, then unlocking will not occur even by pressing the corresponding button.
By the way, the G2 in the lineup of LG is at least the second device with rear-mounted controls. The first was the LG KE / KU 990 Viewty camera phone, which went on sale back in 2007, i.e. at the dawn of the formation of touchscreen phones. In this model, a special ring was used around the camera module, the rotation of which in one direction or the other made it possible to decrease or increase the volume of the sound, and in the camera application it was used to scale.
The LG G2 has a 5.2-inch display, which is based on a very high-quality IPS-matrix, in the LG nomenclature is called more extensively - "True HD IPS", with a resolution of 1920x1080 pixels, i.e. Full HD, which is the standard value for this year's flagships. The pixel density in this model reaches 423 ppi, which is noticeably higher than the threshold when you can see individual pixels without tools at hand. Thanks to this, the image displayed on the screen is as detailed as possible and even almost invisible details can be seen. The viewing angles are excellent and are almost 180 °, however, in the extreme positions the contrast begins to drop noticeably, and the white color becomes gray. In addition, there is also an insignificant manifestation of the pedigree of the disease of IPS-displays - a departure to warm and cold shades when viewed from an acute diagonal angle. Although in real conditions of using a smartphone, this is almost imperceptible.
The contrast level is quite high. Although the display of black color is quite deep, it is still very far from the level of AMOLED matrices. But the color rendition, on the contrary, is one of the best among flagship smartphones and is distinguished by a more correct display of colors and their shades, which, by the way, is difficult for organics to cope with (in most cases). In addition, the wide range of brightness control pleases, but this process, especially in the automatic mode of operation, has its own characteristics that are inherent only in LG devices. So, from 0% to 39%, the brightness level does not change at all, from 39% to 99% it gradually increases, and from 99% to 100% it instantly switches to maximum. Perhaps this is a flaw in the firmware used and in the following versions the work of the automatics will be corrected, because with manual adjustment there is no such thing, and everything works like a clock. Perhaps it should be so. In this case, the brightness itself is regulated, based on the selected level and degree of external lighting - you have to get used to this. In general, at the minimum level, it is quite comfortable for working in the dark, while the maximum level is more than enough for trouble-free reading of information on a bright sunny day. This is also due to the good anti-reflective filter.
The touch pad, connected via two connectors, is capable of handling up to 10 simultaneous touches and boasts excellent press clarity and high sensitivity, thanks to which there are practically no erroneous actions, and accidental touches at the very edges of the display are correctly filtered. However, the sensitivity is not as high as that of some competitors, which is why the ability to work with gloves is not provided. Finger glide is excellent and residual prints can be wiped off with ease, even with the back of your hand, thanks to the high-quality oleophobic coating.
Sound
One of the most important advantages of a smartphone, which will be especially appreciated by music lovers, is the sound subsystem, represented by the progressive audio chip Wolfson WM5110. Its feature is the ability to reproduce sound with a bit depth of 24 bits at a sampling rate of 192 kHz, which corresponds to the Hi-Fi standard. True, to appreciate all the delights of such a sound, you will have to be generous with high-quality headphones. LG, apparently, understood this, removing standard headphones from the LG G2 package, which probably could not reveal the full potential of the device.
The external speaker, despite the fact that it is one, has a loud and rather good sound quality. Of course, you don't have to expect something special, but with its tasks, namely: calls and notifications, soundtracks for videos and games, it copes very well, but more, in fact, is not required. The location of the speaker on the bottom edge is very correct, because it is not muffled when the smartphone is on the table. And you can cover it while watching videos and playing games only if you tightly grip the device.
The speaker did not show any shortcomings during testing: the quality of speech transmission is pleasant and clear, but no more. In addition, it has a fairly large volume reserve, which will definitely come in handy when you are in a noisy environment.
Unlike the front camera, represented by a completely ordinary 2.1-megapixel module, the main one is based on the more advanced Sony Exmor RS with a resolution of 13 megapixels, a matrix format of 1 / 2.3 ", an aperture f/2.4 and a wide range of features, and innovative for the mobile market segment. Why, LG G2 is the first smartphone from a Korean manufacturer that is able to compete at least on equal terms with flagship models from Samsung, Sony, Apple, Nokia, etc., and even surpass them in some parameters.
LG G2 is the first smartphone on the market with a 13 megapixel module and the presence of an optical image stabilization system, which, by the way, does its job well, i.e. with the elimination of minor hand shake when photographing. Of course, a small-sized system is not able to provide such a level of stabilization, which, for example, is found in "soap dishes", but even it is able to add noticeable smoothness of motion in the video, and it costs a lot. In addition, LG's flagship model boasts an excellent 9-point focusing system borrowed from full-fledged cameras. Thanks to this, as well as the presence of the tracking focus function, the objects captured by the camera are kept in focus, despite their movement in the frame field. If the automation fails and does not want to focus on the desired object, you can point at it with a simple tap on the screen or even make even more reliable manual focusing, which is currently present only in several smartphones from LG and Nokia.
Another feature of the camera is the ability to record video in 1080p at 60 frames per second, as well as the use of Super Resolution technology, a software algorithm that can significantly improve the quality of photos taken using digital zoom by combining several images taken at the same time. We also note that a durable sapphire glass is used to protect the camera module, which is also edged with a slightly protruding rim.
As for the camera application, it has a very rich set of functions that can be accessed in a couple of taps. So, the user has access to: the option of a voice shutter release and shooting with a time delay, adjusting exposure, white balance and ISO, as well as changing the resolution, overlaying color effects and activating the Audio Zoom function when shooting a video (increases the sensitivity to sound in the zoom area and decreases recording interference). There are also a number of shooting modes, among which we highlight: HDR for shooting with a high dynamic range; Shot & Clear, which allows you to remove unnecessary objects from the finished picture; regular and circular panoramas; sporty and night modes... However, there are also disadvantages, which are mainly associated with shooting in low light, when there are problems with color reproduction and a significant drop in fps when photographing and shooting video. We hope that LG will fix these shortcomings in the next updates, and if not, and you are not satisfied with this, then you should pay attention to the modification from xda-developers users. In other cases, the LG G2 camera shows itself with better side and allows you to get very high quality results.

User interface
The LG G2 runs Android 4.2.2 Jelly Bean operating system, which is rumored to soon update to latest Android 4.4 KitKat and that would be very cool. The user interface is branded shell LG Optimus UI 3.0, distinguished by a very rich set of functions and solid possibilities for transforming its appearance, which, by the way, in the initial version does not look very harmonious and general structure quite strongly copies the ideas of the "Samsung" TouchWiz.
The interestingness of the software begins to appear already from the lock screen, on the main screen of which (there may be several of them, and additional widgets can be placed on them) a clock widget is displayed, which has beautiful animation with simulated weather conditions. Up to five applications can be located at the bottom of the display. quick launch, and they can be completely different. The lock screens are switched by swiping to the left, while a swipe to the right always launches the camera.
The customizable unlocking effect, accompanied by the appropriate sound design, looks very nice. There are five such effects in total: ripples with leaves, a drop of dew, particles, a crystal and, least beautiful, a white hole.
The desktop, of which there can be a maximum of seven, is a 5 x 5 matrix and each icon can be doubled in size. Moreover, the official icon of the application can be replaced with some other one, or even a fragment of the picture can be used for this. Long tap on free space desktop provides quick access to applications and widgets (there is also a standard full-screen menu, from where you can search required application and completely delete them from memory), as well as the choice of wallpaper. A swipe from the Home button provides the ability to launch the QuickMemo application and Google service Now.
Given the presence of a large display in the LG G2, the manufacturer has provided one-handed control functions, when activated, the dialer, which has the ability to search for contacts by the first letters or numbers, and the keyboard can be shifted to the left or right edge of the screen.
The notification shade has very rich functionality and, in addition to standard capability on and off different interfaces, provides the ability to display QSlide applications and a compact remote control. Here you can adjust the brightness of the display backlight, the speaker volume level and, in fact, view the notifications. When you hold down the Home button, the open application manager starts, from where you can not only completely close applications, but also go to the task manager. It indicates the quantity running applications with the ability to stop any of them, as well as the occupied and free amount of RAM.
Smartphone settings are divided into four tabs. The first three groups all kinds of settings for wireless networks and wired connections, sound and display, and the last one contains general settings.
Since the proprietary shell contains a really huge number of functions and capabilities, the description of which would take at least one more review, here we will focus only on the most interesting of them, as well as on some applications.
An interesting and very useful function is pop-up windows for incoming events, which display SMS text or information about the caller.
A very impressive feature is Clip Tray - a full-fledged clipboard that can hold up to 20 text or graphic elements. An irreplaceable thing when working with office applications.
Thanks to the Plug & Pop function, when the headphones are connected, a list of applications is displayed at the bottom of the screen (their set can be edited), prompting you to select the one you want, for example, a player. When connecting a USB cable, you are prompted to select one of the proposed actions related to this type of connection.
QSlide is a limited set basic applications, a feature of which is the ability to work in multitasking windows mode in the manner of desktop OS. These programs can be moved around the screen, changed their transparency and size (only some), as well as expanded to full screen and collapsed back.
Slide Aside is an alternative manager of running applications. In this case, their number can vary from one to three. Switching between them is carried out by using a three-finger gesture with a swipe to the left (to save the program in memory) or to the right (to open it back).
A very useful function, or rather an application, is Quick Remote - a kind of constructor for turning a smartphone into a universal remote control, which has a large number of pre-configured remotes. If the LG G2 could not automatically detect the model, for example, of a TV or music center, then the necessary remote control with the required "buttons" can be created independently.
Surely many will love the ability to adjust the position. touch buttons, as well as displaying additional ones for quick access to the QuickMemo program and opening the notification curtain without having to reach for it.
We also suggest that you familiarize yourself with the appearance of some applications.
Hardware platform and performance
LG G2, among other things, is also one of the first smartphones to be equipped with the most efficient processor at the moment - Qualcomm Snapdragon 800 in MSM8974 modification. It is manufactured using a 28nm manufacturing process and includes four proprietary Krait 400 cores based on the ARMv7 microarchitecture and running at a nominal 2.26 GHz clock speed. The L2 cache is 2 MB. The GPU-integrated Qualcomm Adreno 330 solution is used as a graphics subsystem, which has support for API DirectX 9.0c and OpenGL ES 3.0. The graphics adapter works at a clock frequency of up to 550 MHz. This set is supplemented with 2 GB of 32-bit dual-channel LPDDR3-800 RAM and a 32 GB drive (there is also a more affordable model with 16 GB of internal memory) without the possibility of expansion via microSD cards. The user has 24.8 GB available.
A separate item should be noted for the first time used in mobile devices graphic memory GRAM (Graphic RAM), which in LG G2 is a kind of cache located in the chain between the graphics adapter and the display. According to the manufacturer, this memory can reduce the power consumption of the graphics adapter by 26% when displaying a static image that does not require constant refresh at a frequency of about sixty times per second, as it happens when displaying a dynamic image, for example, in video and games. In general, the presence of GRAM adds up to 10% to the autonomy of the device, which is a pretty good indicator.
Not surprisingly, with such characteristics, the LG G2 shows some of the better results in almost all synthetic tests. The smartphone is not good enough only for tasks that require an even more productive graphics subsystem, but they all relate to benchmarks, for example, Basemark X and GFXBench (T-Rex HD scene), which, in fact, are created in order to squeeze out of the platform all possible juices.
Even in the most demanding games at the moment, the resources of the Qualcomm Snapdragon 800 are more than enough. Dead Trigger 2, Real Racing 3, Asphalt 8: Airborn, Plants vs. Zombies 2 easily confirms this. There is much more important role plays the degree of optimization of the game itself for a particular hardware and software platform, as well as a productive cooling system that does not allow the processor to warm up to the level at which throttling begins, i.e. lowering the operating clock frequencies. And not everything is so smooth with the latter in LG G2 - the automatic system cuts the frequencies quite strongly, which is especially noticeable after several consecutive runs of AnTuTu Benchmark. But the body of the smartphone remains only pleasantly warm, even with prolonged loads. At the same time, the quality of displaying games does not deteriorate.
The operating system itself works as smoothly and very quickly as possible, however, many of its functions, which are directly related to the proprietary LG Optimus UI 3.0 shell, which require more serious optimization, occasionally jam. However, this phenomenon is observed only in the first seconds after launching a particular function, for example, when opening the notification curtain, when scrolling through quick settings or when opening some applications. And this is quite annoying if you know about this problem and constantly try to fish it out. Otherwise, you may not even notice that something is not working as well as it should.
Communication and communications
The smartphone is capable of working in all modern mobile networks: GSM, WCDMA / HSPA + and LTE. The quality of 2G communication is excellent in both directions: there are no interruptions or spontaneous drops, and the voice transmission is clear, but depends on the user's location.
The set of communication capabilities of LG G2 is very rich and includes almost all modern data transfer standards. So, there are Bluetooth V4.0 with A2DP support, dual-band (2.4 / 5 GHz) Wi-Fi with support for 802.11a / b / g / n / ac protocols and Wi-Fi functions Direct and Wi-Fi Hotspot, as well as NFC, IrLED (infrared), DLNA and Miracast interfaces. In addition, there is support for USB-OTG and USB-Host standards, thanks to which you can connect external drives to your smartphone.
Concerning direct work Wi-Fi module, everything is fine here. Searching for points and connecting to them occurs almost instantly, and established connection has good stability and does not try to "fall off" when strong interference appears. The data transfer rate on the home network is quite fast. In the heavily clogged 2.4 GHz band, it reaches 40-50 Mbit / s (with a total wired line of 100 Mbit / s).
Positioning on a global map of the world provide GPS systems With A-GPS support and GLONASS. The search for satellites, provided that the user is in an open area, takes a few seconds, during which there are about 15-25 pieces. Connecting to them takes a little more time, and in most cases, communication is established with only half of them.
Autonomous work
The last, but almost the most important feature of the smartphone is the use of an innovative lithium-polymer battery, which is distinguished by a special "stepped" shape and the use of silicon oxide as an anode, not graphite (SIO + technology). As a result, this made it possible to make the most efficient use of the internal space of the LG G2 case and accommodate a 3000 mAh battery (11.4 Wh), which is noticeably more than that of many competitors.
In total, such a charge is quietly enough for up to two days of battery life with a fairly active use of the smartphone's capabilities: 5-7 hours of display operation, always-on Wi-Fi module, several hours of Internet browsing, about one hour of talking, 2-3 hours of listening to music , one hour of games, etc. on trifles, but subject to the use of automatic brightness control of the backlight, set at a level of no more than 70%.
However, when performing resource-intensive tasks (for example, games) and setting the maximum display brightness, you can discharge the battery in a few hours, which is confirmed by AnTuTu Tester, in which, by the way, the LG G2 received a pretty good score of 503 points, discharging up to 19% in 2 hours 48 minutes. Much more interesting is the result of looping HD video playback using the MX Player with half the brightness of the display backlight and the Wi-Fi module- more than 14 hours. At the same time full charge battery from the complete charger is about 3-4 hours.

Outcomes
Over the past year, LG's position in the global smartphone market has strengthened significantly, and this is definitely the merit of cooperation with Google in the framework of the Nexus project. In addition, the bar for the quality of its own products has also risen, which is proved by the latest models of devices, among which are rightfully the best flagship of this year - LG G2.
This model boasts not only interesting and in many respects innovative hardware and software solutions, like: really convenient buttons on the back of the case, a wonderful display with incredibly narrow side frames, a capacious "double-layer" battery, a very powerful processor, a wide range of wireless interfaces, a good camera with optical image stabilization, a high-quality audio chip, the ability to unlock with a double tap on the screen etc., but also at a very attractive cost for official version with a 32 GB drive, which dropped to 5777 hryvnia ($ 692).
Of course there is in LG G2 and disadvantages. The most important of them is the easily soiled glossy case, which is covered with fingerprints at an incredible speed and is prone to abrasions, as well as a not very well thought-out cut of the earpiece that constantly collects dust. The rest of the shortcomings are not so significant, and almost all of them are software, which means that in the next updates they may sink into oblivion.
Advantages:
- the best indicators of the dimensions of the case in relation to the diagonal of the display;
- a remarkable 5.2-inch display with Full HD resolution and the narrowest possible side bezels;
- productive hardware platform;
- excellent sound subsystem;
- good camera with an optical image stabilization system;
- implementation of the block of rear buttons and the KnockOn function (unlocking with a double tap);
- excellent battery life;
- support of all types mobile networks(2G, 3G, 4G);
- support for all popular data transmission standards, including Wi-Fi 802.11ac and IrDA;
- support for global positioning systems GPS (A-GPS) and GLONASS;
- support for USB-OTG and USB-Host;
- functional proprietary shell LG Optimus UI 3.0;
- the ability to control almost any household appliances;
- low heating of the case under active load.
