Android: secret codes to open hidden menus
All Android devices have hidden menus. Far from masking hidden secrets,
these allow to explore functions generally reserved for manufacturers, or even
operators who would like to modify a specific parameter (such as the frequency
used, etc ...) via specific secret codes.
we offer a guide to the main secret codes for Android devices.
List of the main secret codes on Android
Be aware that some of these commands may
change the behavior of the smartphone while others can simply erase all data
from the device (randomly the Full Reset and assimilated function). Note that
these codes are functional on Samsung, LG, Motorola, HTC, Sony and other brands
To use it, just open the phone calls
application and type the codes as if you were dialing a phone number. The
execution should be done in stride. If nothing happens, it does not work on
this device. Some codes work on some devices and not on others and vice
versa.

the repair service of a manufacturer.
