android_robotOur 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 formation, instantly back up your precious data, and much more.

The code entry procedure is really 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 codes, don’t stay on it, just move on and find another one.

Basic 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.
