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.
