All our Android devices have hidden menus. Far from hiding shameful secrets, they allow the exploration of functions usually reserved for manufacturers or operators who wish to change a specific parameter (eg frequency used, etc …) through a specific secret codes.
The interest of these codes is often minor but we love so much to discover the bowels of our precious jewels. It is in this perspective that we offer you a guide of the main secret codes for devices running under Android.
List of the main Android secret codes:
Before “having fun” with all these little wonders, be aware that some of these commands can change the behavior of your smartphone, while others may simply delete all device data (such as the Full Reset). Note also that these codes are functional on Samsung devices (like the Galaxy S5), LG, Motorola, HTC, Sony and other brands.
Furthermore, the codes depend sometimes from the used smartphones or even the version of the operating system installed. We have tried to compile what said “universal” codes but your device may not respond to all of them. Last tip, back up personal data and history to avoid any disappointments.
To use them nothing more simple, just open the phone call application and enter the codes as if you are composing a phone number. The execution should take few seconds. If nothing happens then the code does not work on your device.
