- 1. Complete Information About your Phone
- *#*#4636#*#*
- This code can be used to get some interesting information about your phone and battery. It shows following 4 menus on screen:
- Phone information
- Battery information
- Battery history
- Usage statistics
- 2. Factory data reset
- *#*#7780#*#*
- This code can be used for a factory data reset. It'll remove following things:
- Google account settings stored in your phone
- System and application data and settings
- Downloaded applications
- It'll NOT remove:
- Current system software and bundled application
- SD card files e.g. photos, music files, etc.
- Note: Once you give this code, you get a prompt screen asking you to click on "Reset phone" button. So you get a chance to cancel your operation.
- 3. Format Android Phone

- 5. End Call/Power
- *#*#7594#*#*
- This one is my favorite one. This code can be used to change the "End Call / Power" button action in your phone. Be default, if you long press the button, it shows a screen asking you to select any option from Silent mode, AirPlane mode and Power off.
