1. Complete Information About your Phone  

*#*#4636#*#*

 This code is used to get some  really interesting information about your phone and battery. It shows following 4 menus on screen:

  3. Format Android Phone

    *2767*3855#

  5. End Call/Power

  *#*#7594#*#*

  This one is my favorite one. This code is used to change the “End Call / Power” button action in your phone. By 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.
