Hidden Secret Codes for Android Phones

One of the most common practices amongst today’s software developers is to leave certain kind of “backdoors” within operating systems. These “backdoors” essentially allow any users with sufficient knowledge to get into the system at a much deeper level than you’d expect from normal users. These backdoors aren’t always meant to be used for malicious intent, as they allow programmers to get into the system for troubleshooting when other usual access modes have been blocked. And to developers, they can be quite friendly and helpful if you know what you’re doing.

Smartphones also have a good share of backdoors as well, but they’re generally known as “secret codes”. These numeric/symbolic sequences allow you to access hidden menus, diagnostic tests etc. for various uses. And for those devices that run on Android, certain codes are shared across the board, and therefore can be used on a variety of devices.

We’ve listed a collection of some of the hidden secret codes for Android phones. To use these, simply open up your phone’s dialer and punch in the characters as shown.

Now, since most hidden menus are manufacturer specific, there’s no guarantee that they’ll work on your specific device, but you can try them out nevertheless on your Samsung, HTC, Motorola, Sony and other devices. Be advised, though, that some of these can cause serious changes to your device’s configuration, so don’t play with something that you don’t fully understand.

Note: Once you enter the code, the corresponding menu/function should automatically open. If it doesn’t, this means that you’ve either entered the code incorrectly, or your device doesn’t support the code.
