U MUST CHECK~~ANDROID SECRET CODES

        Android secret codes and hacks are fun and even useful if you need to troubleshoot some problems on your phone, but they are not as impressive at most other phones since the phones can already do pretty much everything but there are still some codes which are not always general knowledge. I am posting all the working codes.

The two most useful things here is the ability to confirm that you Android device battery is still working properly and being able to force your Android to stay on 3G without falling back to EDGE or GPRS if the signal is better. If you have any Android secret codes and hacks please send them to, the more the better.
