Secret Hack codes for Mobile Phones:
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 ( How to maximize or boost Battery life in android phones)
- Battery history
- Usage statistics
2. Factory data reset
This code can be used for a factory data reset. It’ll remove following things:*#*#7780#*#*

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. 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.
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.
