Android Operating system has some secret codes that you can use to access to get to some features of your device. If you have loaded Airtime before using USSD codes like * XXX #, this is the same principle. These are characters to type on your phone to access information, do tests or access hidden menus. Let’s see what it is and how to use it.
Let’s start by explaining what is USSD (Unstructured Supplementary Service Data). It is a protocol that allows information to be sent across the network. It is for example possible to recharge your phone in call credit in certain countries. Thanks to this protocol, we buy a card, we scratch and we enter the code.

Want even more secret codes or hidden menus? Did you know that Android offers well-hidden Developer Options? Go to Settings, then to About phone (or System> About phone ), find the Build (or version) number and tap it 7 times. You will see a message stating that Developer Options are available. You will find them in System or directly in the Settings menu. Here you can activate Debug Mode, manage Bluetooth, configure the animation scales, the notch, the background apps, and a lot of other things..
