Access hidden info on your Android device with these secret codes

Your Android device holds a large amount of information about its hardware and system that an average user might find difficult to access. But if you know Android's secret codes , you can factory-reset your device, find out its hidden camera information, instantly back up your precious data, and much more

The code entry procedure is very simple and only requires you to bring up your dialer keypad and enter the appropriate number sequence. Bear in mind that some codes are carrier-specific, and 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.

Generic Android secret codes

These codes are mostly universal, and should work on Android devices, no matter the manufacturer. There might still be carrier restrictions on certain codes though, so they're not all guaranteed to work.

 *#06# - IMEI (International Mobile Station Equipment Identity) number - essential in case your device is stolen and you want to block the thief from accessing your network
