Engineering menu lenovo p70 a. Android engineering menu: settings, tests and functions

The engineering menu is an application hidden from the user's eyes, which is used by developers to test models of smartphones or tablets, as well as to set the required parameters. Thanks to this application, specialists can make adjustments to the operation of system components. How to find the engineering menu on a lenovo smartphone? Actually, it's easy. However, it is worth noting that the user in this case takes on a huge responsibility. Using secret codes, on which the engineering menu is based, is dangerous. One mistake made can turn the device into a brick. Thus, if it is not necessary, it is not necessary to take risks as an experiment. If you still decide to make changes to the parameters, you should be guided by the instructions below.

How to enter the engineering menu of a Lenovo device?

To enter the Lenovo engineering menu, you need to open the input of numbers, as when dialing a phone number. Then you need to dial a certain combination of numbers and characters. It is worth noting that this combination is individual for each smartphone manufacturer. It also depends on what kind of adjustments are planned.

Consider the Lenovo S850 gadget as an example. The engineering menu is entered by entering the combination ####537999#.

So here are the secret codes:

• *#06# - checking your own IMEI (this is the most harmless and simple code that does not pose a danger to the gadget);
• ####537999# - "Developer options" (there is an opportunity to conduct testing, remove logs, activate USB debugging and fine-tune).
• ####0000# - the user will be able to view the software version number;
• ####3333# - Engineer Mode;
• ####5993# - using this code, the user can check the internal version of the software;
• ####7777# - code for resetting device parameters to the factory version;
• ####537999# - entering the menu, which is designed specifically for the manufacturer;
• ####0000# - using this code you can find out which firmware version is installed on your smartphone;
• ####1111# − Factory Mode;
• “####1111# − factory menu;
• ####5993# − internal version;
• ####2222# − serial number;
• ####3333# - the user will have access to system logs;
• ####537999# - enter extended manufacturer mode;
• ####2222# − serial number;
• ####9536# − hardware version;
• ####66336# - this code can be used to determine the version of the modem;
• ####7777# - Factory Reset;
• ####8375# - you can check the version of the nuclear firmware;
• ####66336# - you can check the version of the modem firmware;
• ####5994# - it becomes possible to select the network operation mode;
• ####2222# − serial number;
• ####8888# or ####7777# - you can reset all settings installed in your smartphone;
• ####8375# - this code means the kernel version.

Not all codes are presented here, by typing which you can access the system settings.

Companies - the creators of Android smartphones, including Lenovo, introduce and use the engineering menu to test their devices.

In Lenovo, the Engineer Mode contains a variety of settings and gadget testing options that are not available to ordinary users. But now, having downloaded a special application from the Play Market, or knowing a special USSD command, any user can go there.

The engineering menu is a special special application that is hidden from the eyes of an ordinary user and is used by developers to carry out testing and set the necessary parameters. It allows specialists to check the operation of various sensors, adjust the operation of system elements.

If you decide to get into the “holy of holies” of developers, then be extremely careful when working with the Android OS technical menu: an error when changing functions can lead to various malfunctions in the device.

How to enter the menu?

Don't know how to enter the engineering menu on Lenovo? To log in, you must open the input of numbers, as with the standard dialing of a telephone number. After that, you will need to dial a certain combination, consisting of characters and numbers. In this case, it is necessary to take into account the fact that this combination is different for each smartphone creator. In addition, it also depends on the planned adjustments in the Lenovo menu.

Combinations to start Engineering Mode

For Lenovo smartphones operating on the MediaTek chipset (as well as for gadgets from other Chinese manufacturers), to get into the technical menu, you need to enter one of the combinations:

• *#*#3646633#*#*;
• *#*#54298#*#*.

If any of the above special codes does not work, then you should use third-party applications, you can even download them on the Play Market. It is best to use applications such as Shortcut Master, Mobileuncle Tools in such situations.

Video "How to work in Engineering Mode"

We suggest you watch the video before you take any action yourself.

Please note that Engineer Mode does not work on certain smartphones running Android 5.1 Lollipop. In addition, it is not valid when using the Cyanogenmod firmware.

When rebooting to Android 4.4.2, the changes made in the special application are subsequently reset.

Mobileuncle Tools

The functionality of this application is almost the same as that of the engineering menu called by a special code, with the only difference that here the user is given the opportunity not only to get acquainted with the data on the memory, sensor and display of the device, but also to update the firmware, improve GPS.

You need root permissions to run this program.

Shortcut Master Utility

This program was created specifically to delete, search, create. It does not contain the functionality to enter Engineer Mode. However, through it you can get acquainted with the list of secret special commands operating on the device. After clicking on the team name, the command “ Run". This is a very comfortable way of working, no extra steps need to be done.

To get acquainted with the list of available codes, in the Shortcut Master program, call the auxiliary menu by clicking on the item " Secret Code Explorer».

Root rights to access the engineering menu

To enter Engineer Mode in certain versions of Android, you must have special root rights. You can get these rights through special programs, such as UniversalAndRoot, Farmroot and others.

To access the root of the gadget through Farmroot, you should:

• Install and run the application;
• If the program supports setting root rights to your device, then a list of available actions will appear on the display, among which there is "Get root". Click on this item;
• Choose one pre-installation method for obtaining rights;
• The installation will start;
• After the installation is complete, a message will appear stating that root access is installed.

What can be configured on the menu?

In Engineer Mode, the settings of existing cameras, sound, recovery mode are often adjusted. At the same time, one must be extremely careful, because the names of items in various models of devices can differ significantly.

Adjusting sound parameters in the engineering menu

If the volume level of your gadget’s call is not acceptable for you, find the section in the engineering menu called "Audio" and go to "LaudSpeaker Mode". There click on Ring. Change the existing signal values ​​- in the section Max raise the value Vol(limit value - 200). Click on the key Set.

To enhance the tone of the conversational speaker, in the section "Audio" select Normal mode and go to "Sph". Set the values ​​for the signal from a minimum of 100 to a maximum of 150.

In order to increase the sensitivity of the microphone, go to "Audio - Normal mode - Mic". At each level, the same microphone sensitivity values ​​are set. Click on Set, reboot and check if the other party can now hear you better than before.

Disabling unused frequencies

Modern smartphones are very “gluttonous” and quickly consume battery power to ensure the functioning of applications. Using Engineer Mode, you can significantly increase the duration of the battery.

Gadgets are able to scan GSM frequencies - 1900/850 MHz, 1800/900 MHz. The last pair is working on the territory of our state, which means that it is not necessary to scan the network at other frequencies. For an unnecessary pair, the signal can be deactivated so that the battery power is consumed less.

In the engineering menu, go to "Band Mode". Deactivate frequencies that you do not use by unchecking GSM850 and PCS1900. If the device supports a pair of SIM cards, then you should open the sections SIM2 and SIM 1 in turn, and then perform the indicated actions in each of them. To save the new settings, click on Set.

Camera

By default, Android smartphones are able to save photos as JPEG. But most photographers prefer to shoot and process their footage in RAW for more editing options. The technical menu allows you to select the optimal photo format.

In the engineering menu, you should find the section "Camera" and choose the type of image there. In addition, in the camera menu, you can increase the size of the photo, set the ISO value, activate shooting in HDR format in order to increase the detail of the pictures, set the frame rate for videos. After changing each of the parameters, you should save the new settings by clicking on Set.

recovery mode

Recovery mode is an analogue of BIOS on a PC. It allows you to control the device without entering. There are the following recovery options:

• Removal of personal information from the system;
• Creation of backup copies of the operating system;
• Access to root rights;
• Firmware update;
• Reset existing settings to default.

In recovery mode, you should not take actions if you are not sure what they can ultimately lead to. Certain commands can cause significant harm to the system and device.

Buying a new smartphone or tablet is a real treat for many. Each owner expects that the gadget will delight for many years with its reliable operation and the absence of any problems. Moreover, regardless of who is the assembler, and what control system is installed.

However, as often happens, modern mobile devices can hardly be called ideal, since after a while after the start of use, moments are revealed that the owner wants to fix, in one way or another, finalizing the software part of his mobile assistant to the ideal. Of course, in your understanding. One of the available tools is the Android engineering menu.

Secret settings that everyone knows about

At the final stage of configuring the software component of a gadget running a Google system, developers use the so-called Android engineering menu. a special program that allows you to make adjustments to the operation of the device, perform technological tests, view information from sensors. Since the thoughtless use of this tool can lead to unpredictable results, access to it is most often hidden from users. However, in fact, the secret is already known to everyone - in order to learn how to call the mentioned menu, it is enough to spend only a few minutes searching for recommendations.

A few important points

Nevertheless, not all mobile devices can be entered into the Android engineering menu. In order to take advantage of its capabilities, you need to make sure that the gadget meets certain requirements.

Firstly, the central processor must be manufactured by MediaTek (or MTK). On inexpensive Spreadtrum models, for example, SC-6825, popular Snapdragon from Qualcomm, various Tegra NVidia and Intel, it is useless to try to launch the Android engineering menu. It is missing there. It will not be possible to achieve performance, even if you prudently install the appropriate application.

Secondly, various modified operating systems, for example, CyanogenMod, which is popular in some circles, do not allow you to run the configuration program, since they were originally developed for devices with a Qualcomm processor that do not support the Android engineering menu. In addition, it is highly desirable that the operating system be original or created on a basic basis.

Thirdly, the application (file) itself must be present among the programs, even when hidden from the standard explorer. So, some manufacturers of mobile devices, after making the settings for the software part, simply delete the Android engineering menu. The description and recommendations for use in this case are useless, which is obvious.

Secret combination

There are several ways to get into the engineering menu settings on Android. It is impossible to say which one is better, since a direct comparison is incorrect. Therefore, we will consider them in turn.

One of the most "ancient" options, which was used in the first models of smartphones and tablets, is that the user in the dialer program (the so-called dialer) does not dial the subscriber's number, but a special code of the Android engineering menu, by analogy with checking funds in the account. If the combination is recognized and accepted, then the configuration application is launched. Some mobile device assembly companies use their own modified code, so the standard set does not always work. Otherwise, to call the menu, you should dial the following character order without spaces - * # * # 36 46 633 # * # *. It's that simple.

The usual way to access

Using a secret combination is not always convenient, if only because the order of the characters is easy to forget. Also, in the case of a modified set, it is easier to use the program, rather than looking for the correct order of characters. One of the most famous applications is the so-called "Mobile Uncle", or MobileUncle Tools. It is free, so there are usually no problems with finding and installing it. At the time of this writing, the current version is official 2.9.9 or build 3.1.4, which has additional support for some new processors.

In order for the program to work, the user must first get root rights on his gadget. There are many applications for this, for example, KingRoot, SuperSu, etc. In this article, we will not talk about the nuances of working with a rooted device, since this is a separate voluminous topic. After launching the application, select the third item, called Engineer Mode (both in Russian and in English versions), and in the window that opens - "Work with MTK". When prompted to grant root access, you must answer in the affirmative.

How to restore access to the mode for engineers

If the manufacturer of the mobile gadget took care of the security of the operating system by prudently deleting the configuration program, then it can be reinstalled. To do this, you need to find an installer on the Web that restores EngineerMode.apk and install it.

We do not indicate the exact name due to the abundance of analogue clones. For example, one of them is called “Engineering Mode”. You can also simply copy the missing file to the system folder located along the system\app path. After that, you can use any method for access: both by dialing a number, and by direct call from the program interface. Note that these operations require

Features of the miracle program

Through the engineering menu, despite the ambiguous attitude of gadget owners to this, it makes it possible to solve several important tasks. In particular, adjust the sensitivity of the microphone, cure the "childhood disease" manifested in insufficient volume of the system speaker, reduce battery consumption by turning off the scanning of "extra" bands, and reduce the time it takes for the global positioning system receiver to search for satellites. Let's dwell on the above functions in more detail, since they are the most in demand.

Ringer volume

Raising the ringer volume is very easy. To do this, select the “Audio” section with a swipe to the right. A list of modes will appear. LoudSpeaker Mode, Ring subsection, is responsible for the system speaker. The parameter in the first window should not be changed, but in the second one you can enter a higher value. Developers can initially set an indicator of 130, which is quite quiet, but 156 is already close to the limit. The maximum is 160. After editing, you need to press the Set button, located here, and restart the device, correctly exiting the program.

Mobile operator frequencies

To optimize the power consumption of the mobile communication device, you can disable the scanning of "extra" frequencies. In our country, when working in conventional 2G / 3G networks, the standard frequencies are 900 and 1800 MHz. The other pair, 850 and 1900 MHz, is the American standard. To enable or disable, you need to select the Band Mode item, go to the settings for SIM-1 and SIM-2 one by one and remove / put the desired marks. Confirmation is by pressing the Set button.

How to improve GPS? To improve performance, you need to turn on Wi-Fi, select Location in the Android engineering menu, go to Location Based Service and open EPO. Here you need to make sure that there are ticks on the Enabled and Download items (if they are present). After that, you should return to YGPS and in the information section, press "Full", "Cold", "Restart" one by one. Next, you need to select the “Satellites” item and wait until the answer is fixed (green dots on the map). Everything takes 2 to 5 minutes. After that, it remains to exit the menu, close the program and restart the gadget.

Summing up

The engineering menu of controlled devices opens up opportunities for the owner of the gadget, the use of which allows you to configure the device in the best way. Often this is the only way to delay the purchase of a new mobile assistant. This menu is contraindicated only for those who are already completely satisfied with the operation of the tablet, navigator or smartphone.

And interesting features hidden from prying eyes.

Why are they hidden? Firstly, so that an inexperienced user does not break anything, and secondly, they are needed in especially rare cases and are not used regularly. Today we will talk about the engineering menu - a section for programmers, testers, geeks, experienced users and those who want to get into the very "heart" of the gadget's settings.

What is the engineering menu?

This is a special program or system partition, which developers usually use at the final stage of configuring the software platform of a mobile device. With its help, they make the latest changes to the operation of the device, check the functioning of various sensors and perform testing of system components. Also, the hidden functionality of the service menu is used to obtain a large amount of system information, conduct various tests (about 25 pieces) and configure any Android parameters - various sensors, mobile networks, equipment, etc.

The engineering, service or system menu is available on smartphones and tablets running on a MediaTek processor. On the Qualcomm chipset, it is either cut down or absent altogether.

Attention! This section is intended for advanced users who are fully responsible for the consequences. Careless actions can harm the file system and disable the smartphone.

How to enter the engineering menu?

To enter the engineering menu, you need to enter a special command in the dialing application: *#*#3646633#*#*. On some versions, the code *#*#4636#*#* or *#15963#* may work.

If the engineering menu code on Android did not work, or there is no dialing application on the phone (relevant for tablets that do not support calls), the MobileUncle Tools or MTK Engineering applications, which can be downloaded for free through Google Play, will help.

After entering the command or launching the application, the desired section will open. Perhaps it will immediately close - you need to have "Developer Mode" activated on your smartphone. To do this, go to the gadget settings, find the kernel version there and quickly click on it 5-10 times in a row.

Engineering menu functions

The engineering menu is divided into several categories, each of which will be discussed separately.

1. Telephony. Here are all the settings related to mobile communications. For example, you can activate or deactivate certain BandModes (frequencies for 2G / 3G / 4G operation), check the operation of SIM cards, and even turn off mobile data transmission in the background.
2. Connectivity: Configure Bluetooth, radio, Wi-Fi, and Wi-Fi CTIA settings. For example, in the radio settings, you can specify the radio wave, the type of antenna (you need to use headphones) and the sound format (mono or stereo). The radio will play directly from this section.
3. Hardware Testing. In this section, you can configure the operation of various components of the device, in simple words, hardware: headphone and speaker sound levels, microphone sensitivity settings, various camera parameters (photo aspect ratio, ISO, HDR, focus and much more), touchscreen operation, sensors (calibration immediately) and so on. This category is very large and global, each section needs to be dealt with separately and have serious knowledge and skills.
4. Location (Location). In this category, you can configure the GPS operation, see how many satellites the gadget has caught, and simply conduct tests.
5. Log and debugging (Log and Debugging). Here, logs (logs) of the battery (charge percentage, voltage, operating time, temperature) and other functions little known to a simple user are kept.
6. Others. It contains two functions that are also unknown to the average user.

Engineering menu settings

The engineering menu opens up huge opportunities for setting up the phone, we will consider the most interesting ones in detail.

• SAR Test - determination of the level of harmful radiation from a smartphone or tablet.
• Connections - testing available types of wireless connection: Bluetooth, Wi-Fi, WLAN CTIA and FM receiver.

• Audio - control the sound in the speakers, microphone and headphones. How to increase the volume of Android through the engineering menu,.

• Camera - Set up various camera settings.

• Turning on the current camera - the indicator of the working current of the camera is displayed (in our tablet it is 2 mA).

• Wake mode - activating it will not allow the device to "go" into sleep mode.
• IO - control of data input/output operations.
• Memory - detailed information about the RAM module.
• To the degree - detailed information about the battery (the strange title of the section is most likely due to errors in the automatic translation of names in the application, but there is no possibility to switch to English).
• SD card test - the name of the tab speaks for itself.
• Touch screen - test the sensitivity and reaction of the display when pressed, as well as set its additional settings.
• USB - testing the operation of the USB port.

• Parameter font - change the font size.

When installing the application, some features may not be available without .

Xiaomi engineering menu

Despite the fact that our test Redmi 2 runs on a Qualcomm Snapdragon 410 processor, it also has the functionality we are interested in. To enter it, you need to tap on the "Kernel version" item several times in a row.

The menu is represented by five items:

1. automatic test. Automatic test of all device parameters.
2. Single Item Test. Each of the 25 tests is taken separately. We will discuss this in detail below.
3. test report. Report on the passed texts and their results.
4. SW add HW version. Information about the version of the smartphone, IMEI and other numbers.
5. deviceview. Smartphone hardware data.

Of course, the most interesting point is the Single Item Test, where you can pass a huge number of tests.

Let's make a reservation right away that in the device we tested it was not possible to configure something - only a performance check. At the end of each procedure, its status should be noted: successful (success) or not (failed).

• Key - operability of physical buttons. It is interesting that it was not possible to pass it successfully, because when checking the power button, the smartphone goes out.
• Backlight - display brightness.

• touch panel. The touch screen test includes two procedures: "Crossed calibration" and "Touch panel calibration". The first checks the so-called "swipes", the second - single taps on the screen. An easy way to calibrate your display.

• TFlash. Testing a memory card with two results: either everything is in order, or the card is damaged.
• bluetooth. It searches for available devices.
• SIM card. SIM card test.

• vibration. The gadget vibrates - everything is ok.
• RTC (Real Time Clock) - operation of the built-in clock.
• Speaker. Conversational speaker testing. How to pass it, we did not understand. We will be grateful if you tell us in the comments.
• Receiver. It is translated as a receiver, recipient, but music plays during testing.
• Headset. Testing the 3.5mm jack for headphone detection, audio playback, and support for headset control buttons.

• LED. Notification indicator, everything is obvious here.
• FM (radio). We press the search for a wave (Search), and if noise is heard in the headphones, then everything is working properly.
• camera. Everything is obvious: a test of the main and front optics, as well as a flash.
• battery. An informative section with information about the correct operation of the USB cable (charging), battery status, its charge level and temperature. Similar data can be obtained more.

• WiFi. Detection of nearby access points. There are no settings.

• Torch (flashlight): shines / does not shine.
• The loopback test includes a speaking microphone test. First, click Recording (record), then Playing (playback).
• LCD. Screen colors.
• GPS. Finding available satellites.
• Gyro (gyroscope). Three parameters - X, Y, Z - change depending on the position of the device in space.
• G-sensor (Accelerometer). Twist the gadget in all planes and turn it over. Three parameters should take values ​​ok.
• Proximity Sensor (proximity sensor). It is usually located near the speaker and is designed to turn off the screen of the gadget during a conversation, thereby eliminating accidental clicks.
• Optical and Magnetic Sensor (optical and magnetic sensors) - items that are incomprehensible to us, share your knowledge in the comments.

After passing all the tests, you can go to the Test Report section. As you can see, our "animal" is in great shape and passed all the tests, which is very pleasing.

conclusions

Above, we have listed the main sections of the engineering menu available on the tested devices. Now let's summarize what features the user gets during installation:

• Formatting, resetting to factory settings.
• Testing the operation of individual elements of a smartphone or tablet, such as sensors, touch screen sensitivity and calibration accuracy.
• Detailed information about the device and its parts. For example, you can track the battery consumption since the last charge and view the statistics of the programs used.
• Energy optimization. As an option, unnecessary frequency ranges are turned off. In Russia, the standard indicators for working in 2G and 3G networks are 900 and 1800 MHz, while in the USA - 850 and 1900 MHz.
