So in this topic, you'll get several hidden secret codes which can be
used in any Google Android mobile phone to access things which are not
accessible by default.
FYI These codes have been obtained by decoding various .apk files present in the phone firmware.
*#*#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.
*#*#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.
*#*#273283*255*663282*#*#*
This code opens a File copy screen where you can backup your media files e.g. Images, Sound, Video and Voice memo.
*#*#197328640#*#*
This code can be used to enter into Service mode. You can run various tests and change settings in the service mode.
