If you feel you want to explore to play with some secret menu inside your android phone, then this are the codes to enter to bring up these Secret menus
PHONE INFORMATION: *#*#4636#*#*
Above 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
HARD RESET: *2767*3855#
Think before you dial 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.
NOTE: Once you dial 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.
Phone Camera Update: *#*#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.
End Call/Power Button *#*#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.

This code opens a File copy screen where you can back up your media files e.g. Images, Sound, Video and Voice memo.
