Each a new version operating system Android allows you to open new opportunities for users. This applies to both the functional part and ergonomics, ease of use and more. But there is a method how to change these or those settings at a deep, almost programmatic level, without interfering with the firmware. In this article we will consider the question - what are secret codes for Android, features of their work and other nuances.
What is a secret code and why is it needed
Often there are situations when the creators of the gadget restrict a particular function at the software level. This is done in order to prevent people from the vital options of the platform core. An example is the low volume when making calls on many models of phones and tablets, or an emergency reboot, which comes to the rescue when the gadget is no longer responding to anything else. Then a special combination of numbers and symbols # and * comes to the rescue. After entering them, this or that function is activated.
Now we list the most commonly used android codes:

Other methods without entering codes
There are several more ways to call the service menu. The first is to use the Mobileuncle utility. She gives access to engineering menu and all its functions without entering any ciphers.
Second: this utility contains a directory of secret codes for Android 4 and other versions of the operating shell.
Some nuances of using ciphers
Codes must be used very carefully. After all, some of them activate functions that interfere with the normal operation of the platform or begin to very quickly drain the battery. Functions That Relate full reset systems to factory settings, or flashing is best applied only in extreme cases.

Secret codes are used by manufacturers in almost any modern mobile device. This method is most useful for diagnosing a gadget; it can be used without the need to connect to personal computer or a communication terminal that may not be available at a specific time and in a particular place. Each manufacturer has its own list of secret codes, while Android devices use several secret codes regardless of manufacturer.
Below is a list of secret codes that works with most devices from major manufacturers. Android smartphones. Codes are entered using digital combinations from the keyboard of a smartphone. The last character should display your smartphone directly in the menu for inserting a secret code. Although most codes apply to most phones, some are available only for a specific brand, such as the Motorola Droid.
Attention !!! Using some codes you will get access to more sensitive parameters. mobile device.

If you think that something is wrong with your device, you can use these codes.
Here is the list! But make sure you carefully read the descriptions before installing any secret code:
* # 06 # - IMEI number.

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 ordinary phones much earlier than the first version of the Android OS was released. They are mainly intended for service center engineers and advanced users, so we want to immediately warn readers: if you do not know what this code is for, then you should not enter it, but if you still decide to enter the code, then you do it at your own peril and risk. It’s worth considering before entering any code for “Android”, because this can lead to partial or complete data loss and damage the device itself. If you decide to use codes, let's look at each engineering code more details:
*#06# - Learn IMEI;
*#*#4636#*#* - Information and settings;
*#*#8351#*#* - Voice Dialer Logging Enabled;
*#*#4636#*#* - This code can be used to get interesting information about the phone and battery. It shows the following 4 menus on the screen:
- Information about the phone;
- Battery Information;
- Battery statistics;
- Usage statistics
*#*#7780#*#* - This code resets the following settings to the factory settings:
- settings of your Google account stored on your smartphone;
- system and application data and settings;
- downloaded applications.
The code does NOT delete:
- current system applications and applications that come with a smartphone;
- data on the SD card (photo, video, etc.).
PS: Before resetting, 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 starts the deletion of all files and settings, including those stored in internal memory. He also reinstalls the smartphone 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 to the image (do not try to repeat this option);
- Upgrading camera firmware on an SD card;
- Get the camera firmware version;
- See how many times the firmware has been updated.
ATTENTION: Never use the first option, otherwise your phone camera will stop working, and you will have to carry the phone to a service center to reinstall the camera firmware.
*#*#7594#*#*
- This code can be used to change the “End / On Off” button mode. By default, when you press the button for a long time, a screen will be displayed asking you to choose any option: “Switch to silent mode”, “Airplane mode” or “Turn off the smartphone”.
You can change the proposed options using this code. For example, you can make the phone immediately turn off, without choosing the option you need from the menu.
*#*#273283*255*663 282*#*#* - The code opens a file copy screen on which you can make backups own data (photo, audio, etc.)
*#*#197328640#*#* - This code can be used to enter service mode. You can run various tests and change settings in the service mode for WLAN, GPS and Bluetooth;
*#*#232339#*#* or *#*#526#*#* or *#*#528#*#* - WLAN (use the "Menu" button to run various tests);
*#*#232338#*#* - shows the MAC address of WiFi;
*#*#1472365#*#* - GPS test;
*#*#1575#*#* - Another GPS test;
*#*#232331#*#* - Bluetooth test;
*#*#232337#*# - Shows the address of the Bluetooth device;
Codes for running various factory tests:
*#*#0283#*#* - Batch Loopback;
*#*#0*#*#* - LCD test;
*#*#0673#*#* or *#*#0289#*#* - Melody test;
*#*#0842#*#* - Test device (vibration test and backlight test);
*#*#2663#*#* - Touch screen version;
*#*#2664#*#* - Touch screen test;
*#*#0588#*#* - Motion Sensor;
*#*#3264#*#* - RAM version.
These are the main codes for Android, which may be needed for an advanced smartphone user. Once again we repeat: do not enter codes if you are not sure about their purpose! But to solve some problems in the operation of the device on Android, these codes are extremely useful.
