*#*#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


*#*#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 applications

SD card files e.g. photos, music files, etc.


PS: 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.

*2767*3855# Think before you give this code. This code is used for factory format. It'll remove all files and settings including the internal memory storage. It'll also reinstall the phone firmware.

PS: Once you give this code, there is no way to cancel the operation unless you remove the battery from the phone. So think twice before giving this code.

Update camera firmware in image (Don't try this option)

Update camera firmware in SD card

Get camera firmware version

Get firmware update count



WARNING: Never use the first option otherwise your

phone camera will stop working and you'll need to take your phone to

service center to reinstall camera firmware.




*#*#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.


You can change this action using this code. You can enable direct

power off on this button so you don't need to waste your time in

selecting the option.
