What are secret codes for?
Secret codes have been implemented on Android in order to obtain information on the technical characteristics of a device without having to consult the serial number. These codes can for example be used to obtain the IMEI number of a telephone, the MAC address of the Wifi or Bluetooth module but also to check if the telephone is blocked (Simlocker).
Certain codes also make it possible to test the various components of the smartphone . These diagnostic tools are used for example to detect a fault on the touch screen, the proximity sensor, the microphone or even the speakers..
Even if most of these codes are not dangerous for your smartphone, some can modify the configuration of your mobile or even delete all the data on the device. These secret codes must therefore be used with the greatest caution.
You should make a full backup of your smartphone to avoid any inconvenience. getFastAnswer and the author of this article cannot be held responsible in the event of problems, blockage or malfunction following the use of these codes. Use it at your own risk..
