I ran across some interesting information detailing undocumented codes for many Android phones. You input the codes using the dialer to access phone features and information normally unavailable. The codes were obtained by decoding various .apk files present in the phones firmware.
The website “Tweaking with Vishal” details a number of codes, some of which must be used with caution as they can modify functionality, delete data or alter firmware.
The code I listed in the title gives you phone and battery information. I tested the code on my Samsung Galaxy S. It list 4 items in the menu:
- Phone information
- Battery information
- Battery history
- Usage statistics
Make sure you read and head the authors warning before entering the other codes. You can get a complete set of codes here.
