Many users of Android smartphones and tablets are not even aware of the existence of so-called engineering or service codes. Service codes appeared on smartphones and regular phones much earlier than the first version of the Android OS was released. They are intended mainly for service center engineers and advanced users, so we immediately want to warn readers: if you don’t know what this code is for, then you shouldn’t enter it, and if you still decide to enter the code, then do it at your own peril and risk. It is worth thinking before entering any code for Android, because... this may lead to partial or complete loss of data and damage the device itself. If you decide to use codes, let's look at each engineering code in more detail:

*#06# - Find out IMEI;

*#*#4636#*#* - Information and settings;

*#*#8351#*#* - Voice Dialer Logging Enabled;

*#*#4636#*#* - This code can be used to get interesting information about your phone and battery. It shows the following 4 menus on the screen:
— Phone information;
— Information about batteries;
— Battery statistics;
— Usage statistics.

*#*#7780#*#* - This code resets the following settings to factory settings:
— your Google account settings stored on your smartphone;
— data and settings of the system and applications;
- downloaded applications.
The code does NOT remove:
- current system applications and applications supplied with the smartphone;
— data on the SD card (photos, videos, etc.).
PS: Before resetting the settings, the smartphone will ask for confirmation, so until the very last moment you will have a chance to change your mind.

*2767*3855# - Think before entering this code. This code is used for factory formatting, that is, it triggers the deletion of all files and settings including those stored in internal memory. It also reinstalls the smartphone’s firmware.
PS: After entering the code, there is only one way back - quickly remove the battery and start data recovery via PC.

*#*#34971539#*#* - This code is used to obtain information about the phone's camera. It shows the following four parameters:
— Updating the camera firmware into the image (do not try to repeat this option);
— Updating the camera firmware on the SD card;
— Get the camera firmware version;
— See how many times the firmware has been updated.
WARNING: Never use the first option, otherwise your phone camera will stop working and you will have to carry your phone in service center to reinstall the camera firmware.

*#*#7594#*#* - This code can be used to change the mode of the End/On/Off button. By default, when you long press the button, a screen will be displayed asking you to select any option: “Switch to silent mode,” “Airplane mode,” or “Turn off smartphone.”
You can change the suggested options using this code. For example, you can make the phone turn off immediately, without selecting the desired option from the menu.

*#*#273283*255*663 282*#*#* - The code opens a file copy screen where you can make backups your data (photos, audio, etc.)

*#*#197328640#*#* - This code can be used to enter maintenance mode. You can run various tests and change settings in service mode for WLAN, GPS and Bluetooth;

*#*#232339#*#* or *#*#526#*#* or *#*#528#*#* - WLAN (use the Menu button to run various tests);
*#*#232338#*#* - shows MAC address WiFi;
*#*#1472365#*#* - GPS test;
*#*#1575#*#* - Another GPS test;
*#*#232331#*#* - Bluetooth test;
*#*#232337#*# - Shows the Bluetooth device address;

Codes for running various factory tests:
*#*#0283#*#* - Batch Loopback;
*#*#0*#*#* - LCD test;
*#*#0673#*#* or *#*#0289#*#* - Melody test;
*#*#0842#*#* - Device test (vibration test and backlight test);
*#*#2663#*#* - Touch screen version;
*#*#2664#*#* - Touch screen, test;
*#*#0588#*#* - Motion sensor;
*#*#3264#*#* - RAM version.

These are the basic codes for Android that an advanced smartphone user may need. Let us repeat once again: do not enter codes if you are not sure of their purpose! But to solve some problems in the operation of the Android device, these codes are extremely useful.
