[] Do You Know About Android's Secret Codes?

Hi Mi Fans,
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.

Secret Android system codes
Some 'secret' codes are Android 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. These 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.

Warning! These codes should be used with caution. They can make your phone lose data, or render it unusable. There's a lot of incomprehensible tech jargon which pops up in the menus after entering some of these codes, which means that if you aren't 100 percent sure what you're doing, don't do it.


List of secret codes for Android
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.

Only way is to factory reset it, you will lose the data that isn't backed up, but you'll be able to use the phone again
