Commands to access the menu

Commands to access the engineering menu vary depending on the manufacturer. There are also general commands for all Android versions, allowing you to configure individual device functions.

Main codes for entering the engineering menu

Entered commands differ for different brands of devices - select those that are suitable. It is not forbidden to check all - not the corresponding to the specific manufacturer of the team simply will not work.

Table: Commands for access to the engineering menu of various manufacturers

Commands provided by Google for Android OS

Android factory service codes showing technical information About the device, often do not have bindings to the manufacturer. Basically, they are all "sews" in the default Android. The group "Numbering" teams is agreed by Google - on the rights of the Android operating system - with manufacturers of tablets and smartphones.

When using commands, you must consider the following:

updating the camera firmware through the engineering menu, you can learn about the version of this firmware and the number of its updates - as well as save this update to the image in the internal memory and on the SD card. Remove the camera is not recommended once again - in case of failure, you just turn it out;
when resetting the Android system with deleting all user google data A message-request message will appear on the screen to confirm the reset.

How to enter the engineering menu

To get to the engineering menu, follow these steps.

What to do if it did not work in the menu

It happens that none of the teams intended for a particular brand of devices are not suitable - this manufacturer does not protect experienced users From not to the end of thoughtful actions. Some manufacturers after the smartphone program debugging completely remove the engineering menu, and all the above commands simply do not work. For example, this makes Samsung. Some of the commands input can harm both the Android software and the device itself.

Often, instead of common service teams, more specific are triggered. If, despite all your attempts to "reach" to the engineering menu, none of the service codes is triggered - special applications are needed.

Install free app MobileUncle Tools - It will demarcate hardware and system settings. It may be necessary to get root-access on Android. There are other applications: ENGMODEMTKSHORTICUT, BETTERCUT, etc.

How to Save Settings

So that the settings made using the Android engineering menu are preserved, you need to go out correctly. Being in any of the sections of the engineering menu, use the "Back" screen or in the menu itself, or press the Call Cancel button or the Back "below the display - it is indicated as an arrow with a reversal - to exit the level of the engineering menu.

It is not recommended by setting the value of any setting and confirming it with the SET key ("Set"), turn off or restart the smartphone by pressing the power button, pull out the battery from the device, etc. The output from the engineering menu can be pressed on For a few seconds - the same "Back" key, which is under the display. When you exit the engineering menu on the smartphone screen, a request message will appear about the need to save the generated settings - confirm it. There are tips on some of the sections of the engineering menu:

The reason why the engineering menu still does not save the settings may be "raw" firmware. Find out which versions and android assembly Suitable for your device. If you have a branded smartphone with the version of Android, which has pre-installed programs and components from Beeline, MTS, MegaFon or Tele2 - boldly establish a "custom" version, for example, a well-known CyanogenMod assembly. There may be any earlier - or, on the contrary, the most "fresh" version of Android.

In some cases, enter the engineering menu is impossible without getting root rights. The task is to make a smartphone with Android "rutted". In other words, get the "superuser" capabilities on the smartphone, allowing you to take a smartphone for the most clear and complete control. This is achieved in the following ways, use any of them.

Install on your smartphone custom (modified) version of Android. Its composition already includes the SuperUser software component ("Super User"), which opens access not only to the engineering menu, but also to the System system folder.
Load from Android Market any of the Android hacking applications without the help of a computer. Different programs are suitable here: Universal Androot, Unlock Root, Z4ROot, Revolutionary, etc., not all of them can help - have to test everything until it turns out.
You can also try Windows applications that do directly with PC all manipulations with root-access on your smartphone - for example, VROOT program. You also need a USB-MicroUSB cable - Wi-Fi hack Android on the smartphone is impossible.

After receiving the root privileges, the smartphone is ready to activate the engineering menu using third-party android applications.

The "Fresh" version - the more settings in the engineering menu will be in Russian. In the earliest versions of Android (1.x, 2.x), all service settings were in English. A little learn technical English, you can easily remember the purpose of each of the settings and if necessary, you can change them all in a few minutes.

The availability of the engineering menu is in whole or in part, it decides not the Android version, but the brand and model of the smartphone. Try different combinations and programs, but not too fond.

With ineptive actions or for the forgetfulness of the input codes, there is a risk of turning the smartphone into a lifeless machine, and only in the service center you can restore it. And since in the case of "rutting" of the device you automatically deprive the warranty.

Engineering menu Android is one of the most useful tools "advanced" user who does not allow it to waste the hardware resource of its device and a cellular resource and wireless networks Wasted. And no matter what your version of Android is 2.2, 4.2.2, 4.4.2 Kitkat, 5.1, 6.0 or other, the engineering menu codes are determined only by the manufacturer. Fully subordinate to my smartphone or tablet, you will deprive it with the ability to "live your own life" not according to your schedule, but according to the manufacturer itself, cellular operators and other intermediary companies, one way or another involved in work mobile technology In cellular networks. This is the soastful way to professionalism.

And interesting features hidden from prying eyes.

Why are they hidden? First, so that the inexperienced user does not break anything, secondly, they are needed in particularly rare cases and are not used regularly. Today we will tell about the engineering menu - a section for programmers, testers, gickers, experienced users and those who want to climb into the most "heart" of the gadget settings.

What is an engineering menu?

We are talking about a special program or system sectionwhich developers are usually used at the final stage of configuration of the mobile device platform. With it, they contribute last changes In the work of the device, check the functioning different sensors and perform testing system components. Also hidden functionality service menu Used to receive large number system information, conducting various tests (about 25 pieces) and setting any Android parameters - different sensors, mobile networks, equipment, etc.

Engineering, service or system menu is available on smartphones and tablets operating on the MediaTek processor. On the Qualcomm chipset, it is either trimmed or absent at all.

Attention! This section is designed for experienced users who are fully responsible for the consequences. Careless actions can cause harm file System And bring their smartphone to the smartphone.

How to log in the engineering menu?

To enter the engineering menu, in the number dialing application you need to enter a special command: * # * # 4646633 # * # *. Some versions can work the code * # * # 4636 # * # *.

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

After entering the command or start the application, the desired section will open. Perhaps he immediately closes - it is necessary that the "Mode for Developers" can be activated on the smartphone. To do this, go to the gadget settings, find the versa of the kernel 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 described separately.

Telephony (Telephony). Here are all settings concerning mobile communications. For example, you can activate or disable specific Bandmode (frequencies for 2G / 3G / 4G), check the operation of SIM cards and even disable mobile data transmission in the background.
Connectivity: Configure Bluetooth, Radio Receiver, Wi-Fi and Wi-Fi CTIA. For example, in the radio settings, you can specify a radio wave, an antenna type (you need to use headphones) and sound format (mono or stereo). Radio will play straight from this section.
Hardware Testing. In this section, you can configure the operation of various components of the device, simple words, Iron: Headphone and speaker sound levels, microphone sensitivity setting, various camera parameters (color aspect ratio, ISO, HDR adjustment, focusing, and more), the operation of the touchscreen, sensors (calibration right there) and so on. This category is very large and global, in each section you need to understand separately and have serious knowledge and skills.
Location (location). In this category, you can customize the operation of GPS, see how many satellites caught the gadget, and just conduct testing.
Log and Debugging (log and debugging). Logs (magazines) of the battery are underway here (the percentage of charge, voltage, time of work, temperature) and other little-known simple user functions.
Other (Others). Contains two also unknown to an ordinary user function.

Settings for engineering menu

The engineering menu opens up huge opportunities to customize the phone, the most interesting we look at in detail.

SAR TEST - determining the level of harmful radiation from a smartphone or tablet.

Xiaomi engineering menu

Despite the fact that our test REDMI 2 works on the processor Qualcomm Snapdragon. 410, in it, too, is the functionality of interest. To come to it, you need to tap the "kernel version" item several times.

The menu is represented by five items:

AUTOMATIC TEST. Automatic test of all device parameters.
Single Item Test. Each of the 25 tests is separated separately. We will tell about it in detail below.
Test Report. Report on the texts and their results passed.
SW Add HW Version. Information about the version of the smartphone, IMEI and other numbers.
Device View. Data on smartphone equipment.

Of course, the most interesting item is Single Item Test, where you can go through a huge number of tests.

Immediately alleged that in the device we tested, there was no possibility to configure something - only the inspection of performance. At the end of each procedure, it is necessary to mark its status: Successful (Success) or not (Failed).

Key - performance physical buttons. Interestingly, it did not work successfully, since when checking the power button, the smartphone goes out.
Backlight - display brightness.

TouchPanel. Test Screen Test includes two procedures: "Crossed Calibration" and "Touch Panel Calibration". The first checks the so-called "swipes", the second is single clicks on the screen. A simple way to calibrate the display.

Ring check includes a test microphone test. First, click Recording (recording), then Playing (playback).
LCD. Screen colors.
GPS. Detection of available satellites.
GYRO (Gyroscope). Three parameters - x, y, z - change depending on the position of the device in space.
G-sensor (accelerometer). Screw the gadget in all planes and turn it over. Three parameters must take OK values.
Proximity Sensor (approximation sensor). Usually it is located in a conversational speaker and is intended to have a gadget screen, thereby eliminating random pressing during the conversation.
Optical and Magnetic Sensor (optical and magnetic sensors) - incomprehensible items, share knowledge in the comments.

After passing all the tests, you can go to the Test Report section. As you can see, our "animal" in excellent form and all checks stood, which is very pleased.

conclusions

Above, we listed the main sections of the engineering menu available on the tested devices. Now we generalize what options the user receives when installing:

Formatting, rollback to factory settings.
Testing the work of individual elements of a smartphone or tablet, for example, sensors, sensitivity of the touch display and the accuracy of calibration.
Detailed information about the device and its parts. For example, you can track the battery consumption since the last charging and view the statistics of the programs used.
Optimization of power consumption. Alternatively, unnecessary frequency ranges are disconnected. In Russia, standard indicators for work in 2G and 3G networks are 900 and 1800 MHz, while in the USA - 850 and 1900 MHz.

Secret codes for Android devices! Using entering these codes, you can get information about any android smartphone and tablet, or change its settings. I would like to note that with some codes you need to be very careful, since after applying the previous settings you will not succeed.

Many android users Smartphones and tablets do not even suspect the existence of so-called engineering or service (secret) codes. Service codes on smartphones and on ordinary phones Appeared much earlier than the first version of the OS android was published. They are intended mainly for engineers of service centers and advanced users, the poet immediately want to warn readers. If you do not know what this code is, it is not necessary to enter, and if you still decided to enter the code, then you do at your own risk. It is worth thinking before entering any code for android, because This can lead to partial or complete loss of data and fail the device itself. If you accepted the solution to use codes, let's consider each engineering code.
Remember that not every code is universal and will work on all devices. Below we present you a list of the most common and most sought-after combinations for Android devices.

Secret combinations for information about the phone and tablet!

These are basic codes for androids that may need an advanced smartphone user.

Engineering menu opens access to manual setting "Iron" part of the smartphone. To enter you need to enter special code Or install the application, but there are a number of features that you should pay close attention. If you could not enter the engineering menu from the first time, then did not take into account the features of the device. It is necessary to immediately clarify that any interference with the operation of the device can lead to its inability and loss of warranty.

Hidden system capabilities

In the last stages of the smartphone setting, the developers test the system for errors and check the operation of all device sensors. Especially for this in Android, a special subprogramme is sewn - an engineering menu that provides access to hidden settings Android OS and allows you to reconfigure them yourself. In addition, the menu is deployed device information. The full list of menu features is known only to the platform developers, so your changes should be made with caution.

Secret trails of developers

To enter the engineering menu, type the code * # * # 3646633 # * # *. On some models, you must additionally press the call key. It is worth considering the features of the phones: for different brands there are various combinations of numbers. Android version Does not affect the engineering menu functionality.

Enter a special code to enter the engineering menu

If there are no problems, you will fall into the additional menu for fine-tuning smartphone.

We enter the subsection menu

Depending on the system version and processor model, the engineering menu can be incomplete or absent. In the photo above, the menu subsection with the test elements of the smartphone sensors, the USB connection setting, the execution of tests of internal and external memory.

If the first time did not work

Not all devices are included in the engineering menu. Consider a number of common problems and ways to eliminate them.

Android is a complex operating system based on UNIX. If something does not work, you did not take into account all the nuances of the functioning of a subprogramme.

List of special codes

One of the common reasons for blocking the entry into the engineering menu is the wrong special code. The combination of numbers depends not only on the device model, but also on the processor type. For example, most of the MTK chip database devices are equipped with an engineering menu. If we talk about Qualcomm, far from all smartphones on the basis of this platform sewn engineering menu. The list of combinations is shown in the table. If you did not fit the desired, try entering another combination.

Table: Code options for different Android models

Engineering menu do it yourself

If no special code approached, do not be upset. There are many applications with an engineering menu functionality. It is worth noting that the MTK attack in the names eloquently talks about compatibility only with MediaTek processors.

First option - MobileUncle MTK Tools. In this program, in addition to the necessary set of settings there are several additional features: Firmware update, Recovery update, GPS receiving mode and more.

MobileUuncle MTK Tools provides settings

Another program is MTK Engineering Mode. The program completely repeats the regular engineering menu.

MTK Engineering Mode repeats the regular engineering menu

For those who have a device not equipped with an engineering menu, there is another option: the installation of third-party firmware. In assemblies of third-party developers, there is very often a wide range of "Underway" settings.

Where to begin

When you first enter the menu, you can get lost in the rapids of the parameters.

Settings for engineering menu

Settings open huge opportunities for users.

Depending on the hardware platform, some items may not be available or absent.

In this section, you can configure mobile parameters.

Auto Answer. Available on-off automatic response to an incoming call.
Band Mode. Allows B. manual mode Select the frequency range for the operation of the GSM module. You will see all the technologies and frequencies for them supported by your smartphone model. If you wish, you can remove the checkboxes from the ranges that are not used by your telecom operator. This will significantly save the battery charge. To save the settings, press the SET button.
CFU Setting (CALL FORWARDING SETTINGS). The option enables or disables conditional redirection. It must be supported by the operator.
AT Command Tool. Utility for developers supporting AT commands. This menu item will be interesting for programmers and developers. With this menu, you can perform various requests directly to the system without visual add-ons.

Setting the volume of speakers

In the subsection, you can configure the overall volume level, the volume of headphone playback and speakerphone.

A change in volume parameters should be treated carefully. All parameters are individual for a specific device model. Incorrect configuration It may lead to the deterioration of indicators of hearing.

There are a number of common parameters:

MAXVOL - the overall volume level. Range of values \u200b\u200bfrom 0 to 160. The greater the number, the higher the volume.
SPH - Volume when telephone conversation.
MIC - microphone sensitivity.
Ring is the speaker volume with an incoming call.
Media is the volume level when watching movies, listening to music and games.

Very often, users are dissatisfied with the volume of the speaker when talking. To improve audibility, go to the Normal Mode menu and change the SPH parameter to 150. If the phone is quietly called with an incoming call, then you need to increase the Ring parameter value. We advise not to put the value above 200, this may lead to the output of the dynamics. To be better audible, change the MIC parameter from 100 to 172. This will increase the sensitivity of the dynamics.

Root - Panacea for smartphone

On a smartphone without root rights functionality Engineering menu is limited: some items are not displayed, the changes made are not saved. For any intervention in the work of the smartphone required open access in the system. Do not forget that getting root access can harm your gadget, the warranty on the device is canceled. We strongly recommend backup important information On the memory card and to synchronize with Google Account and remove it to avoid data loss. For unlocking full access You can use one of the existing methods.

Installing the application directly to the device (Kingroot)

Suspector access can be opened with a smartphone using special programs. Consider the sequence of operations on the example of the Kingroot program:

After that, you can safely change the parameters in the engineering menu, all changes will be saved. In the case of a negative result, we turn to the following method.

Obtaining superuser rights through PC (Kingo root)

This method is distinguished by a little more preparatory activities:

The engineering menu is used to configure the device and test the work of the Iron Filling. This is a sewn system subprogramme, which is an indispensable tool for both advanced users and newcomers in the world of mobile devices. However, it should be noted that the manipulation with the engineering menu can lead the gadget into a non-working condition.
