Some secret Android codes are system codes and usually begin with an asterisk or a pound symbol/hashtag. These don’t require you to be connected to a network to use them, since they’re just for the Android system on your device. Secret Android codes are updated regularly as new versions of Android software are released, and some manufacturers have their own additional special codes.
The code entry procedure is very simple and only requires you to bring up your dialer keypad and enter the appropriate number sequence. It’s important to note that some codes are carrier-specific, so they won’t work on all devices. So if your phone doesn’t respond to a code, don’t dwell on it, just move on and find another one. You are advised to be careful with secret Android codes otherwise they could render your phone unusable.
