Android gadgets are becoming more and more popular among users due to their ease of use and high functionality. But at the same time, not everyone knows about the possibility of more personalized and flexible customization of their phone. For these purposes, the engineering menu is usually used, which includes a number of a wide variety of settings - a program for automatically recording conversations, increasing the volume of the device, a huge number of various add-ons for the radio.

Unfortunately, this menu is not available to everyone. Some manufacturers simply remove the program to enter it at the last stage of the pre-sale Android setup. Also, the engineering menu is available for owners of devices on Android with a processor only from the MTK manufacturer, trying to run it with a processor from other manufacturers is useless.

Special commands and applications

To enter the engineering menu, you must enter " secret code". For different manufacturers, the "activation code" may be different, but there is one universal one that is suitable for almost all ANDROIDs - * # * # 3646633 # * # *.
You need to enter it in the dialing and call window. Most often, immediately after entering the code, you immediately enter, but on some devices, in order to enter it, you may also need to press the call key. If the program does not start, to enter, you can try to enter other combinations for launching, corresponding to your phone model.

Samsung - * # * # 4636 # * # * or * # * # 8255 # * # *
HTC - * # * # 3424 # * # * or * # * # 4636 # * # * or * # * # 8255 # * # *
Sony - * # * # 7378423 # * # *
Huawei - * # * # 2846579 # * # * or * # * # 2846579159 # * # *
MTK - * # * # 54298 # * # * or * # * # 3646633 # * # *
Fly, Philips, Alcatel - * # * # 3646633 # * # *

If all of the above steps were unsuccessful, you can try downloading at Google play special application for starting the engineering menu. If, even after installing a special program (most often "Mobile Uncle"), it was not possible to enter the service menu, it means that the launcher on your phone engineering settings has been removed, you can install it again.

Almost all phones experience software glitches, the source of which may be in the firmware. To identify them and determine the type of breakdown, there is a special service menu through which you can test each module in the phone and identify the essence of the problem.

In this article, we will tell you what the xiaomi engineering menu is, how to enter, as well as the main functions that may be useful to you.

What is the engineering menu and main functions

These are hidden smartphone settings aimed at testing and fixing errors. There are no such settings in the usual menu, because inexperienced users can knock off the correctly set parameters, after which the phone can stop ringing, the connection can be lost, etc. Therefore, be very careful not to harm the system.

Engineering menu on xiaomi redmi 3 phone has the following functions:

Sound adjustment in the main speaker;
Adjusting the sound in the conversational dynamics;
Microphone setup;
Setting up networks;
Camera setup;
GPS testing;
Repair IMEI;
The ability to optimize the system for less battery consumption.

These are not all functions, but rather the main ones that are in the greatest demand.

How to enter the engineering menu

Consider the ways to enter the engineering menu using the example of Xiaomi Redmi note 3 pro. There are only two standard methods. The third option is through applications, which is worth using if the standard methods do not work.

Through settings

Note that this method is universal, it is also suitable for Xiaomi redmi 3s. So, let's go to the smartphone settings. Scroll down, tap on "About phone". We are looking for the line "Kernel version" and slowly click on it three times. Perhaps the inscription "It remains to press two more times" appears at the bottom. In the same way, slowly press two more times.

The "secret settings" look like this (depending on the phone, the view may differ slightly):

With special code

Open the dialing, and dial the code * # * # 6484 # * # *. The same will appear as above in the screenshot. This code Must fit all Xiaomi devices. If nothing happens when dialing this combination, you should try the following codes: * # * # 3646633 # * # * or * # * # 4636 # * # *.

On some other models, the engineering menu looks like this:

If you can't open the engineering menu

If Xiaomi redmi note 3 pro does not enter the engineering menu, then you should use alternative ways entrance, namely special software. Consider two programs that will help you: MTK Engineering and MobileUncle Tools. You can find many more similar applications on your own.

MTK Engineering is a fast and convenient program, it looks like this:

The Android Testing item contains the android settings, namely:

Phone information;
Battery information;
Usage statistics;
Wi-Fi information.

We need the MTK Engineer Mode item - this is the engineering menu itself. The look may be slightly different, but the essence will not change.

MobileUncle Tools is a more powerful program than the previous one, in that it additionally allows you to perform many other operations with the system, however, only for devices with MTK processors, which are not found in all Xiaomi devices.

First, you need to click "Engineering Mode" and then select "Engineering Menu (MTK)". It should be added that this program requires root rights. At the present time, this program has been removed from the Play Market, but it is not difficult to find it on the Internet. Insofar as this application is developed by a Chinese author, you can meet the English or Chinese version.

Conclusion and translation of functions

In conclusion, we want to warn you that you handle the numerous system settings wisely. If you need to repair or check any module in the phone, you should not immediately change the parameters of the engineering menu yourself, it is better to first look for instructions on our website or on the Internet just for your case. For convenience, we have translated all the functions (Xiaomi Redmi Three smartphone was taken as an example).

Standard smartphone settings are not always enough. Maximize the sound, increase the font size, reduce the battery drain - all this can be done only through the Android OS engineering menu. it hidden application is in every phone, and it is intended for developers. We will show you how any user can enter this special mode and change system parameters.

Entering the system engineering menu gives access to a number of settings. Their exact list depends on the model mobile device, its hardware characteristics, the presence of special sensors. Do not forget that changing the system parameters yourself can seriously disrupt some OS functions. Proceed with caution and do not change everything at random, before editing it is better to write down the previous values \u200b\u200bin order to be able to adjust the smartphone.

The general list of system partitions usually includes items:

Telephony - mobile communication.

GPRS - mobile Internet and Sim card;
NetworkInfo - check the quality of the cellular network;
Auto Answer - activation of auto answer to a call;
HSPA Info - 3G network data;
CFU Setting - forwarding settings;
Band Mode - selection of GSM frequencies, unused frequencies can be turned off to save battery power;
RAT Mode - setting the priority communication standard;
Modem Test - test for compatibility with various devices when working as ";
Fast Dormancy - Saves battery on 3G networks.

Connectivity - wireless connections.

Bluetooth - setting and testing the Bluetooth module for receiving and transmitting data;
Wi-Fi - check wi-Fi operation;
CDS Information - parameters of wireless networks;
FM Receiver - FM module test.

Hardware testing - testing of hardware characteristics.

Audio - volume parameters for calls and music, dynamics during a conversation, microphone sensitivity;
CPU Test - checking the functions of the central processor;
ChargeBattery - information about the battery;
Camera - additional parameters of photo and video shooting;
Mult-Touch - enable reaction to multiple presses;
Sensor - calibration touch screen;
Sleep Mode - activation of sleep mode.

The item names and order will differ in different models and depending on the method of entering the Android menu - through service codes or special applications.

How to open

The secret application cannot be launched through the normal interface. How to enter the engineering menu in Android:

open the call window, where you can enter the phone number from the keyboard;
enter a special combination of characters;
if the menu does not start right after entering the code, click on the call button.

Each manufacturer has its own combination of symbols, it contains numbers and special characters *, #. For example, the engineering menu of Samsung gadgets is launched by entering the sequence * # * # 4636 # * # *.

If nothing happened after entering the code, use applications from Google Play that can work with the engineering menu. Most of them will need root rights to the device, without which the program will be unstable, some parameters will become inaccessible.

MTK Engineering Mode

A complete copy of the standard engineering menu.

Mobileuncle Tools

Advanced utility. In addition to viewing and changing basic settings, it allows you to repair IMEI, update firmware and improve the GPRS signal. Displays full characteristics of the sensor, screen, memory.

Launch of the engineering menu of MTK

A utility for devices with MediaTek processors. Successfully loads engineering functions, but errors have been noted when saving parameters - after a reboot, they can be reset.

Another mode for developers is smartphone recovery. It will come in handy in case of problems with the device, serious errors. If the phone does not turn on, you will not be able to get into the regular menu, but you will most likely be able to start recovery mode.

To start, use the combination of the power button and the volume up or down keys. Sometimes you need to press Home additionally. Press and hold the indicated buttons until the download starts.

The most useful item in this mode is wipedata... It launches full reset, returning the device to the factory settings. With this, you will lose all your data and programs, but you will get a clean phone. Resetting will help if you are too smart with the changes in the engineering menu, setting inoperable values.

Examples of

Let's look at a few examples of useful actions that can only be performed in a secret system application.

Additional codes

You can get access to engineering functions in Android without a menu, through special codes. They are entered as a dial-up, allowing you to test hardware components and display technical information about them.

In addition to common codes, a number of manufacturers have their own specific ones:

Sony: ** 05 *** # - reset PUK code;
Samsung: ## 778 - launch system menu;
Motorola: * # * # 2432546 # * # * - check for updates, * # 06 # - show IMEI;
HTC: ## 3282 # - calls system application, ## 3424 # - full test of the gadget, ## 7738 # - protocol check.

It is also convenient to use Secret Codes to work with codes. Install it on the device, the application will start searching for combinations to control the OS and give them full list... To check the value, you do not have to rewrite it; you can launch the function with one click on its name.

Conclusion

We figured out what can be done through the engineering menu and how to open it on Android devices. The secret mode opens up to users the widest possibilities for personalizing the gadget and many options for disrupting its operation. So make changes to system settings carefully. If, as a result, serious errors appear, roll back through the recovery mode.

In smartphones and tablets based on the operating room android systems there is a so-called engineering menu, in which additional device settings are hidden. The settings are usually intended for specialists. However, if desired, a simple user can also use them, for example, to increase the sound on their smartphone.

How to enter the engineering menu? Let's show an example on a smartphone based on an MTK processor (MediaTek).

Open the Phone app.

Dial the following combination - * # * # 3646633 # * # *. The screenshot below is missing a symbol at the end, because when you enter a full combination, the engineering menu immediately opens. If nothing opens for you, try pressing the call button.

The engineering menu has opened in front of you.

Here you will see many different items and parameters, many of which can be changed.

It is worth changing the parameters only if you know exactly what you are doing. If you don't know, it's better not to touch anything in the engineering menu at all - in order to avoid problems.

You can also download an application for MTK. In the Google Play Market, search for mtk engineering mode and you will see many applications that support the engineering menu. The application works only for devices based on the MediaTek processor.

On the Samsung Galaxy The engineering menu is opened by typing the command * # 0011 #. In front of you, you will see this:

To use, click on the "Menu" button on your smartphone and select Back.

Few people know, but in Android there is a menu of advanced settings, the so-called "Engineering menu". And if anyone has heard about this, they may not know how to enter this very menu on Android. It is in this article that I want to tell you how you can get into this section.

Engineering Codes for Android: Video

How to get to Engineering Menu

Entering this menu on Android 4 occurs by entering a special key combination in the dialer, the so-called code, each manufacturer usually has its own combination. So, you need to enter the dialer, and dial:

After dialing the code, the "Engineering menu" should immediately open, if this did not happen, you should try to press the call button.

What features are available

After logging in, a large number of settings will be available (for advanced users). One of the simplest is changing the volume at each level, that is, you can specify what volume will be at the 1st level, which at the 2nd, and so on. This will be useful for phones with standard volume too quiet, making the value higher than usual at the last level. I propose to see everything with an example.

Then select the section "Engineer Mode (Manufacturer)"

Since we need to change the volume value, select "Audio"

Then you will need to experiment with the values, as a rule, the numbers can be set from 0 to 160. Where 0 is absolutely no sound, and 160 is the maximum volume.

Also, you can make many other changes, in theory, almost the entire functional part, for example, adjust the vibration strength of the phone, the strength of the radio module reception, and much more. If you like to experiment, then there is just something to have fun with, just be careful when changing the values, because you are not in the right hands, you can not customize the device for yourself, but, on the contrary, only make it more inconvenient to work with.
This is actually the whole manual on how to get into the advanced settings menu on Android 4. Nothing complicated!
