Despite this apparent growth in mobile technology, there are still some webmasters who are too stubborn to convert their websites to mobile websites.

Website Technology News: Benefits of Converting Your Website to a Mobile-Optimized Website.

In this article, we will start discussing a very hot topic that seems to be very annoying for webmasters, why should we turn an existing website into a mobile website. The first obvious reason is that most websites that have not been converted to mobile sites will not display correctly on mobile devices. You can easily lose repeat visitors and sales in such a situation. For example, if a mobile user is looking for something to buy on your site but finds out that your site structure is loading too slowly, they will certainly go off looking for the item on other mobile websites.

Mobile sites are the best

Why does a website need a mobile version? On top of that, mobile websites are ranked higher in search engines as well. It is clear that in classic search engine optimization (SEO), things have gone too far. But with mobile SEO, it's just the beginning! The largest search engine in the world, Google will actually display results that are optimized for mobile users first. This is how you can get the means to achieve your goals and beat the competition!

With the help of mobile websites, you can be on the spot for your visitors all the time. Most mobile phone users are on the move and looking for information on the go. If you display a phone number on your mobile site, your visitor can call you directly from their mobile device. For example, if you are a restaurant owner, this hungry user appears to be going through your site. He can call the restaurant directly from his cell phone and inquire about food, location or any other information he needs! That's what the mobile site is for.

Now you can see how great it can be to convert your existing website to a website for mobile devices (phones, smartphones, phablets, tablets)!

Before you finish reading, consider some numbers. The world population is 6.7 billion people. Of these, five billion are mobile users. If that's not enough to convince you to convert your site to a mobile website, here's another fact; an incredible 80 percent of these mobile users access the Internet using mobile devices every day! That's four billion users every day. It is undoubtedly clear that the mobile industry is moving very quickly. Within the next two years, the mobile internet will overtake the natural website industry. So friends, don't forget to take care of your mobile site today!

Electronics manufacturer Cooler Master has a range of hardware products such as keyboards, power supplies, headsets, computer (PC) cases, mice and of course coolers. Each of its products has been specially designed based on community feedback. Including hybrid keyboards. Cooler Master even had a Kickstarter project - an analog keyboard with pressure-sensitive keys called the ContolPad. With that said, let's take a closer look at what makes the new Cooler Master SK621 keyboard special for the user.

Keyboards News Today: Cooler Master SK621 Review is a mechanical wireless keyboard with separate wired connectivity option.

The first thing that is noticeable during the review is the ability to conveniently pair the wireless keyboard with three different devices. Connecting a device is as easy as holding the feature button and Z, X or C. This feature makes it very easy to switch from using your phone to your computer. It's easy to turn on the Cooler Master SK621 keyboard too. Either plug it in via a USB Type-C cable, or on the left side, activate a very simple switch to wireless mode.

Cooler Master SK621 Wireless Keyboard Specifications:

You can display a wide variety of colors (shades) to any key, customize lighting modes or customize macros using Cooler Master software.

How does a wireless keyboard work?

When using SK621 for the first time, it is recommended to connect to your computer via USB Type-C and install Cooler Master Portal. This will allow you to control various lighting effects and wireless keyboard settings. It is possible to create preset profiles, which makes it easy to switch between profiles when using elements. You can also adjust the lighting effects using the controls, but the portal mentioned above is more user-friendly. Setting up your wireless keyboard is very easy to use and has many combinations. There are options - adjusting the speed, direction and brightness of the keyboard backlight effects.

Macros can also be programmed. It is also worth adding that all functions such as RGB lighting, macros and controls are also available when using the SK621 via a Bluetooth connection. The battery life of the wireless keyboard is also impressive. It may take a couple of full business days before the indicator turns red, indicating that the battery is low. Charging the SK621 wireless keyboard is easy too. Just plug in your keyboard via USB Type-C. The keyboard can still be used as a wired keyboard while the cable charges the keyboard battery.

The keyboard body is crafted from polished aluminum for a lightweight, durable and premium look. There is also a nice sleek accent around the edge of the aluminum that adds a touch of elegance. The keys are made of plastic and don't have any particular texture.

Low-profile Cherry MX keys are quiet enough for office use. The key switches are incredibly responsive and using the Cooler Master SK621 wireless keyboard takes some practice. This is because the keys register the keystroke with millimeter precision or less.

The SK621 hybrid keyboard is designed to be compact and quite portable. The velvet bag is a nice addition. It's definitely made for gaming with Cherry MX keys, but it's easy to use for work.

The Cooler Master SK621 does everything it is designed to do. However, the keys are great for gaming, but too sensitive for typing. Plastic keys are also prone to oil stains on the fingers, so eating while playing can be challenging. Perhaps if the keys had some kind of oil resistant coating or more texture, the oil prints would not have been as pronounced.

ETH Zurich has released details of "Concrete Choreography", an installation recently opened in Riom, Switzerland. The innovative installation features the first robot-built 3D-printed concrete stage, consisting of columns made without formwork and 3D-printed to full height in 2.5 hours. This process is expected to significantly improve the efficiency of concrete structures while achieving the fabrication of complex material components and construction robots.

3D Printing News: ETH Zurich creates concrete columns using a special 3D printer for printing from concrete.

In Riom, Switzerland, nine 2.7 meter high columns are installed at the Origen Festival. Each column is 3D printed with concrete. The new columns were custom designed with dedicated software and manufactured using a concrete printer, a new automated 3D printing process from concrete developed by the ETH Zurich team with the support of NCCR DFAB.

3D printing from concrete like this

Graduate students in digital manufacturing and architecture explore the unique capabilities of multilayer extrusion printing, demonstrating the potential of computer-aided design and digital fabrication for future concrete construction. Perhaps the construction industry will make this process more sustainable in the future if they develop new eco-friendly concrete for 3D printing.

Video review 3D printing from concrete: Concrete choreography.

Here's how simple and fast concrete 3D printing works.

3D printing of a house, concrete buildings is a perspective for construction.

Hollow concrete structures are printed for strategic use of materials, thus providing a more sustainable approach to specific architecture. In addition, the calculated material structure and surface textures are examples of the versatility and significant aesthetic potential of 3D printing with concrete when used in large-scale structures.

A new review will be about metal printing on a 3D printer.

It is worth noting that there is a technology that would carry out 3D printing with metal. This is also a promising direction for construction, but for this, other materials are used (for example, powder), programs and other types of printers (which, we will talk about soon).

What color is your mobile phone? Is it black, red, white, gold, or blue? Chances are, the back of your phone has some kind of solid color option that you will find in the Starter Coloring Kit. It has taken too long for most phone manufacturers to realize that phone colors are really important to consumers, and only recently have they begun to give mobile phones not only infrequently used colors, but quirky hues like coral red or canary.

Honor News: With the new 3D holographic color phones from Honor, it is possible to add some new color to life.

Unsurprisingly, most people don't mind hiding the backs of their phones behind the opaque plastic of the case. In cases, the user can match the color of the phone case to give the mobile a little personality. But China's new Honor 20 Pro and Honor 20 series phones are the world's first smartphones with 3D dynamic holographic design, and their reflective appearance could become the new industry standard.

"Always better" is the company's motto. This motto is likely to indicate that she refuses to follow the industry standard by simply experimenting with layers of paint on every new phone model.

Color 3D holography for phone case.

In order to achieve a shimmery optical illusion for the phone's body, Honor has designed its Honor 20 with a deep layer containing millions of flickering microscopic prisms, and on top of this is a so-called curved 3D glass layer. The combination of these technologies makes the light "play and dance" on the back of the phone when the user turns it in different directions.

Two colors for the Honor 20 phone can be found under these dynamic layers, they are Midnight Black and Sapphire Blue. Unlike the trendy phrases for some phone colors, Honor Mobile has color gradients for phones that really bring out the effect of a shimmering night sky or a shimmering jewel.

While the body color options sound exciting, the Chinese phone Honor 20 Pro can go a step further. This redesigned model contains the proprietary "Triple 3D Mesh" containing three layers. Instead of just painting the back of the phone itself, this time with a layer of body color, sandwiched between the outer 3D layer and the inner depth layer. As reported by the phone manufacturer, this makes the color shift effects much more dynamic.

The Honor 20 Pro mobile phone is actively sold in two colors such as Phantom Black and Phantom Blue. While the names of these phone colors are not so metaphorical, you shouldn't think that their backs are less dynamic.

Honor's obsession with choosing the right colors may seem overly dramatic, but in the UK, for example, a survey of hundreds of Britons found that forty-nine percent of them consider color when choosing a phone to buy.

Why is selling a phone with a changing color scheme?

What is a phone for? The choice of a mobile phone, as the designer of Honor Jun-Soo Kim put it, is "Extending a person's life." Essentially, Honor is stating that customer identities cannot be captured by a single, unchanging color.

The history of Honor color phones.

The Honor 20 demonstrates the natural evolution of the company's dynamic color experimentation in phone design (iridescent colors). The Honor 8 started the trend of 2.5D type multi-layer back wall, which creates a 3D lattice effect. The Honor 9 then morphed into a 3D curved glass phone, echoes of which can be found on the Honor 20. Well, last year the Honor 10 was equipped with an Aurora rear glass that reflected colors from all angles.

What is the screen on an Honor phone?

Honor's design innovations are not limited to the color of the phone case. The location of the Honor 20's camera is worth paying attention to. Instead of cropping the screen to make room for a selfie camera. The phone manufacturer cut a 4.5mm hole in the upper left corner of the screen, thus leaving more screen space for the user's needs.

Artificial intelligence camera or AI camera in the phone.

As for the description of the phone, it is worth noting that on the back of the device, the Honor 20 AI camera has four lenses and is positioned to leave more room for a battery with more memory. Most importantly, the result is a 48MP camera that uses the Kirin 980 AI microchip to capture DSLR-level photos and enhance photos.

Honor phone color summary.

In summary, phone descriptions, technical compatibility, and cutting-edge hardware innovation are what usually draws attention to Chinese Honor phones. But, in this case, the technology is almost overshadowed by the unique color scheme of the case, which may make some users not want to go back to simple two-dimensional phone case colors in the future.

Rumors continue to surface about the release of the Google Pixel 4 mobile phone. A new set of information or predictions comes from an image leaked on the Internet (3D rendering of color bodies), which is believed to be from the Google Pixel 4. It is not uncommon for users to follow behind the topic of novelties, such images are overlooked. In the meantime, for some analysts, the new picture helps make some assumptions beyond the color of the phone.

A new, unofficial image of the Google Pixel 4 gives rise to rumors of color options for the mobile phone case.

While the other image of the phone itself does not seem to show more than what has already been discussed on the internet earlier, the model seen in the background of the photo is surprising due to the color. That cell phone has a shade of purple that the Pixel didn't have before.

Elsewhere, there have been other leaks of the same Google Pixel 4 with "three phones" (variants) stacked in a row. There are white and black colors plus the third has a bluish tint, which some call mint green. Would you like to buy a blue phone? Probably the name of the phone's colors will still be updated.

As much as true or false about the phone's colors, it's safe to assume that the new Google Pixel 4 will definitely have a complementary color this year. What's even more interesting, in the image, the physical buttons on the sides of the phones contrast with the color of the case. You can see white, blue and yellow buttons which give the phone a funny look.

For some strange reason, all the images and leaks seen so far only displayed the back panel of the Google Pixel 4 smartphone. Various sources reported that Google allegedly shared a rendering of the phone, and there was also a part where the square camera protrusion appeared. The dual camera unit was visible.

The discussed photo leaks, including the image with the cases, show the rear panel in different colors and the camera module. What do you think is the best phone color?

About the technical characteristics of the Google Pixel 4:

Obviously, the idea of ​​a fingerprint scanner doesn't leave fans alone. Some want the phone to have either a face ID to unlock the phone, an in-display fingerprint scanner, or both.

Several other aspects and technical specifications, such as phone dimensions and overall thickness, 8.2 millimeters higher compared to 7.9 mm seen in the Google Pixel 3 and Pixel 3 XL, can be taken as close to reality.

There is speculation that the Google Pixel 4 and Pixel 4 XL versions of the phone may look more like the "Apple iPhone 11" variant slated for release in a couple of months. When, more precisely? Tech company Google has yet to announce an official release date for the Pixel 4, but various sources are hinting at a new phone launch at the end of the year.

Have you ever wondered why you need the latest model phone? We'll have more details on this soon, so stay tuned for more news on new smartphones from Google.

The robot has set the world record for solving the Rubik's Cube. This robot was developed by the students of the Massachusetts Institute of Technology (MIT) Jared Di Carlo and Ben Katz, in the student laboratory. For comparison, the fastest human record is held by Australian Felix Zemdegs, who collected the Rubik's Cube in just 4.22 seconds in 2018. By the way, the original size Rubik's Cube has 43 quintillion possible combinations for one solution. Watch the video with the record-breaking robot below.

Robotics News: Nimble MIT Robot collects Rubik's Cube, keeping within the world time record - 0.38 seconds.

There is a special place in the hearts of many people for the Rubik's Cube. This is a good workout for the intellect. Many people loved or still love to play with this ingenious toy, and over the years there have been many contests, trials and variations for the Rubik's Cube solution.

The popularity of the Rubik's Cube can be attributed to the simplicity of its construction combined with the mind-boggling difficulty of the puzzle.

New record for solving Rubik's Cube 3x3x3.

Engineers and enthusiasts have used robots to assemble Rubik's Cubes for years. In the past 10 seconds was considered a quick build, but by today's digital age standards, this time raises a smile.

The new record was only a matter of time before engineers and robotics began to tackle the challenge of creating a new robot. Back in 2016, the robot set a new Rubik's Cube record in 0.637 seconds. But for some enthusiasts, this time was not fast enough.

More recently, two MIT students, Jared Di Carlo (third-year electrical and computer science student) and Ben Katz (mechanical engineering graduate student), thought they could put together a faster robot that could solve a 3D combination puzzle.

They watched videos of previous robots and noticed that the robot motors weren't the fastest they could use to solve the problem. So we thought they could do better with improved engines and controls.

How the robot collects Rubik's Cube

The students installed an electronically controlled motor that powers each face of the Rubik's Cube. Using a pair of webcams aimed at the cube, special software determines the initial state of each side of the cube (which colors are on which face of the cube at a given time). Then, based on the information received, using the already existing software for assembling the Rubik's Cube, using an algorithm, the robot solves the puzzles.

What is the result of the work? Their robot solved the Rubik's Cube in 0.38 seconds! It is safe to say that not a single person is physically capable of breaking the record of this speed. One more achievement can be added to the list of robots superior to humans.

There is a man who has the fastest world record for hand-assembled, his name is Felix Zemdegs. He was able to solve the Rubik's Cube in 4.22 seconds. The skills and talents that robots are crowding out are vast and varied, to say the least. Not to mention the fact that robots can still amaze. Further, a video demonstration of the robot, it is better not to blink when watching.

Video review of the Rubik's Cube assembly in 0.38 seconds:

So, hardware hackers Ben Katz and Jared Di Carlo broke the previous record for robotic Rubik's Cube collection. Their robot solved the puzzle 40 percent faster than the previous record.

Details about the robot record holder

The robotic device is assembled from the engines of the Kollmorgen ServoDisc U9 series, PlayStation Eye cameras (for scanning the cube) and of course the Rubik's Cube was needed. According to the creators of the robot, - "The entire program process takes about 45 milliseconds. Most of the time is spent waiting for the webcam driver and determining the colors on the sides of the Rubik's Cube."

Artificial Intelligence Research Group Facebook Inc. introduced a new platform for robotics called PyRobot. This platform (framework) was developed in collaboration with researchers from Carnegie Mellon University. PyRobot aims to help AI researchers and students integrate deep learning models built using the PyTorch platform (a machine learning library for the Python programming language) with the robots they build. The basic idea is that they can more easily build their robots using artificial intelligence skills like natural language processing.

News from the world of AI robots: Facebook introduces the robotics platform PyRobot, an open source robot control framework.

Facebook said it wants to promote long-term research in robotics to help develop embedded artificial intelligence systems that can learn more effectively by interacting with the physical world.

Previously, the company introduced the PyTorch Hub to spur production of AI models.

What is PyRobot today

PyRobot is a lightweight, high-level interface that provides hardware independent APIs for robotic manipulation and navigation. The PyRobot repository also contains a low-level stack for LoCoBot, a low-cost mobile robot hardware platform (toolkit for building robots). Now artificial intelligence and machine learning is becoming more accessible to newcomers to robotics.

Academic Supervisor Abinav Gupta and Saurabh Gupta as Facebook Researcher explained in their blog that: PyRobot is a lightweight high-level interface on top of a robot operating system. It provides a consistent set of hardware-independent middle-tier APIs (Application Programming Interfaces) to control various robots. PyRobot abstracts away the details of low-level controllers and inter-process communication, so machine learning professionals and others can simply focus on building high-level AI (artificial intelligence) robotics applications.

A Facebook source also says PyRobot has dozens of potential applications, such as helping researchers share data and set benchmarks and build on each other's work. The company has solicited input from the broader AI research community on how to democratize robotics with LoCoBot and PyRobot, which are both a hardware specification and toolkit for building low-cost robots.

PyRobot works by using an API to abstract away the functions that robots are supposed to use. Perform tasks such as kinematics, path planning, position, speed and torque control for joints, and visual simultaneous localization and mapping. PyRobot comes with a number of pre-trained deep learning models that allow robots to navigate, grab objects, and more.

This means that developers can program their robots with just a few lines of Python code, according to Facebook.

Researchers from Facebook also say that: The cost of hardware and the complexity of specialized software are limiting the scope of robotics research. With lower barriers to entry, researchers can, for example, create multiple robots that collect data and learn in parallel. By providing a common platform for different hardware. PyRobot will lead the development of tests in robotics, similar to other areas in AI, and will quantify the pace of progress in AI robotics.

Like Amazon's RoboMaker tool, PyRobot works as an interface on top of a robot operating system (ROS), extending the infrastructure. Tech company Microsoft released a limited preview robotics toolkit in May, and last year integrated the ROS platform into Windows 10.

When Apple planned to use Intel modems in its iPhones, it was rumored that the iPhone 2020 phone model would be the first to receive 5G connectivity. Since then, however, the Apple company has switched from its modem provider to Qualcomm. For which they had to settle a long patent dispute with an American chipmaker, pay at least $ 4.5 billion and not use Intel modems. Intel may even have closed its 5G development plans after this news.

According to a note from analyst Kuo Ming-Chi, development of the new version of the iPhone 5G mobile phone is proceeding right on schedule. We're supposed to see Apple announce the iPhone 5G in 2020. Also in a note, Kuo mentions that both the 5.4-inch iPhone model and the 6.7-inch iPhone model will have a 5G modem. There is a hint of some kind of update to the iPhone XS and iPhone XS Max smartphones.

Ming-Chi Kuo also said that all three iPhone models in 2020 will come in multiple colors and feature an OLED screen, as opposed to the LCD screen (LCD) in the current iPhone XR. This year, however, we'll probably still get the iPhone XR update with LCD, so if the OLED screen in mobile is too much of a concern for you, maybe wait a year.

5G iPhone competitors:

Currently our best competitors on Android are the following 5G phones:

1) Xiaomi Mi Mix 3 5G (128GB storage, 6GB RAM and fast charging battery)

2) OPPO Reno 5G (innovative design, affordable price, powerful camera);

3) LG V50 ThinQ (screen 1440 by 3120 pixels, expandable memory up to 1 TB, battery 4000 mAh);

4) OnePlus 7 Pro 5G (bezel-less AMOLED screen with no notches or holes)

5) ZTE Axon 10 Pro 5G (48MP camera, Snapdragon 855 chip).

In new articles, there will be a unique video review of 5G phones with prices.

Global sales of 5G phones.

Worldwide shipments of mobile stores with 5G technology (this is a fast mobile communication of the fifth generation) may turn out to be higher than market analysts' expectations. It is worth noting that some mobile market observers believe that such shipments are likely to reach 150-200 million units, or more than a dozen percent of global 5G phone shipments next year.

Facebook has unveiled its new Calibra project, a digital wallet for storing and sending Libra crypto coins.

Through their mobile apps, billions of people are expected to be able to make payments with cryptocurrency from social media giant Facebook. The social network Facebook plans to officially launch a new project of the Libra cryptocurrency in 2020. Libra is a new type of digital money that targets billions of people using mobile apps and social media.

The popular social networking site Facebook has more news for the cryptocurrency world.

To create a new digital wallet that will allow users of the Facebook application to store and exchange cryptocurrency. Facebook creates new subsidiary Calibra.

Why is Facebook betting on a cryptocurrency called Libra? Perhaps the lofty goal of the latest development is to go beyond social networks.

Digital wallets for storing, sending and spending Libra cryptocurrency will be connected to messaging platforms.

Initially, the cryptocurrency will be available in the Facebook Messenger / WhatsApp application, and of course in separate applications for iOS or Android.

In a press release, Facebook said: "Initially, Calibra will make it easy and instant to send Libra at a low cost to virtually anyone with a smartphone."

It also reported that: "Over time, additional services will be offered for businesses and people. For example, buying a cup of coffee with scanning a code, paying a bill at the push of a button, traveling on public transport without having to take cash with you."

Facebook cryptocurrency wallet security.

To increase the security of the new cryptocurrency, it will use similar verification and fraud protection features that are already used by credit cards and banks. Facebook cryptocurrency service will have user support. And in case someone else gains access to the user account, a refund is promised for the lost assets.

Cryptocurrency coins will be stored by users in a digital wallet. But, the world of cryptocurrency itself is not always stable! Time will tell if Facebook's own digital money can help people save money by sending and spending it as easily as sending text messages.

The cryptocurrency will be managed by the founding members: Facebook, more than two dozen different organizations and a separate Swiss foundation.

Why Libra?

What does the word Libra mean?

Former PayPal executive David Marcus, who leads the Facebook project, said something like this: "The choice of the name Libra (Libra) was inspired by several reasons, namely the French word for Freedom, the Roman measurement of weight, the astrological sign of justice."

Surely you have come across the concept of a virtual number more than once and did not understand what it is. Do you know what is its virtuality and how it differs from the usual one? We will understand these issues and find out about its features.

Virtual numbers are a service of a telecom operator that a client receives when purchasing a cloud PBX. Its main feature is that it does not require installation at a specific address. To use a cloud number, you only need a device with Internet access and software that allows you to use it on any device: smartphone, laptop, tablet, PC, etc.

Such a number may have a Toll free code (8-800), the most common city or even mobile. Calls from it can be received on smartphones and tablets through PhonerLite, Zoiper, 3CX, X-Lite programs, and to mobile and landline phones using call forwarding.

What are virtual numbers for?

The answer to this question depends on what purpose the user is pursuing. Some users need this product for a short period of time. They connect / rent it to re-register on social networks to receive the code via SMS. Others use it to avoid spam with multiple registrations / subscriptions on different platforms or to protect against fraudsters. But perhaps the most common motive is the use of communication for business.

The demand for a virtual number for so many ways is determined by the number of its advantages:

1. Low cost. It varies depending on the operator, and calls within the PBX are completely free. Also, their use is much more profitable when making calls abroad.
2. Ease of connection. To connect, no special skills or expensive equipment are required, only Internet access. It will also take a little time to connect such a number, a maximum of 30 minutes, and you are already a full-fledged user.
3. Lack of location. You will not be tied to the office. Even while traveling around the world, you can respond to or contact customers as if you were at the workplace.
4. Reputation building. Your company can be located in any city, but you can purchase a virtual number with the area code with which your company interacts most. So a farmer from the region selling milk to Moscow stores will look more prestigious with a Moscow number than with a local one. Customers will feel more at ease with familiar code. If you want to declare yourself as a large company that cares about the comfort of customers, you can give preference to the number 8 800.

What are the features and benefits of a virtual number?

You might be mistakenly thinking that cloud numbers can only be used to make and receive calls. Everything is much more personalized and interesting.

In accordance with the different preferences and requirements of customers, a virtual number can perform a variety of functions required by a specific user. So you can choose the most suitable one for receiving SMS or free calls, bulk SMS mailings or even organizing multi-channel communication lines to handle a large number of incoming calls.

When you connect to the service, you get a lot of pleasant bonuses in the form of additional services. You can connect a voice menu so that the client can choose which department to contact. Or set up routing to distribute calls to those departments or employees in the order you see fit.

This product can be freely added to the must-have list for modern business. It will help you reduce communication costs and not miss a single client.

Finally

Considering the pros and cons of cell phones, we can conclude that these devices give us many advantages in terms of communication, and also allow us to use advanced functionality in various fields of application.

If this question seems silly, then smartphones are already familiar to you. However, think of the millions of people who have never held this wonderful device in their hands. They use regular dialers. The touch screen, the absence of physical buttons, fragility, large dimensions, the need to charge almost every day - all this will be unusual for them.

The transition from an ordinary phone to a smartphone means a complete overhaul of the model of interaction with a mobile communication device.

If you are going to buy your first smartphone, then first find out what you have to deal with. If it is a gift to someone, then first introduce the person to the device and ask if he needs all this at all.

Have you decided that you still need a smartphone? In this case, you need to determine the parameters of your dream gadget in order to get everything important and not overpay.

Budget

The totality of uncertainty about acceptable spending, poor understanding of the topic and the persuasiveness of the sales assistant can hit the wallet hard.

Any purchase begins with the formation of a budget.

There are thousands of smartphone models. You can get a decent device for 9 thousand rubles, or you can get it for 209 thousand!

If the speed and quality of a wireless connection is critical to you, then you can get confused, buy the necessary equipment and make your "dream grid" at home or at work. Otherwise, you don't need to worry about having 5 GHz Wi-Fi in your smartphone.

Operating system

Windows mobile devices are not worth considering. The power of smartphones is in the range of app stores, and only iOS and Android can boast of them. By the way, there is no particular difference between them.

iPhones are, to put it mildly, not cheap and do not differ in a variety of characteristics. Accordingly, you cannot buy an "apple" gadget, for example, with an increased battery.

The advantage and at the same time the disadvantage of the Android system is that it runs thousands of device models for any budget and needs, and there are only a few actual iOS gadgets.

What is the disadvantage here? Android diversity causes system fragmentation. Someone has a seventh version, and someone still has an A or even a B. Manufacturers often forget about support and updates, but they try to draw their own user interfaces. And they do not always succeed in doing this.

Fragmentation is a headache for Android developers and potential problems for users related to the compatibility and stability of a particular device.

In favor of Android, you can write down a lot of freedom and flexibility of customization, but an ordinary user often needs a convenient system out of the box without tinkering and preliminary settings.

The confrontation between Android and iOS has been going on for a very long time and, it seems, will never end. Gigabytes of text have been and will be written by not-so-smart people in the midst of fierce Internet battles. In fact, the truth is always the same, and it sounds very simple: "Everyone chooses what he likes."

Hold an iPhone and several Android smartphones in your hands. Compare the systems at work and choose the one that works best for you.
