Unlike Blackberry or iPhone devices on Android device you can perform whatever you think a bot can do. Every Android genuine user is an explorer. They love to explore every nook and cranny of their beloved devices. This is why I decided to share you 150 Distinct Android Secret Codes with there functions. The codes will work depending on your device.

The truth is that no device manufacturer will allow all users to have access to some critical settings that can tamper the security of the user. To guarantee 99% Security, Android device code are hidden from all user and provided to developers upon request. However I decided to share this because I know there are some developers or even user here wishing to have some extended settings on his Android. If you are one of those, You are welcome

I will give readers two notes, while one is very important to all those interested in the code should read the other one is also important but not like the first one.
