Note: We'll not be responsible for the use or misuse of this information including loss of data or hardware damage. So use it at your own risk.

*#*#4636#*#*

This code can be used to get some interesting information about your phone and battery. It shows following 5 menus on screen:

• Phone information
• Battery information
• Battery history
• Usage statistics
• Wifi information

Menus might differ for different mobile phones.

*#*#7780#*#*
This code can be used for 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.

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.

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

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

*#*#34971539#*#*
This code is used to get information about phone camera. It shows following 4 menus:

• 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.
