Useful Android Secret Codes You Must Know
Are you having problems
with your device?
Is the touchscreen of
your device less sensitive?
Do you want to format/reset your device because of virus, application error or bugs?
Here are some useful Android Secret
Codes you must know;
––> PHONE INFORMATION;
*#*#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
––> 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 the 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.
––> Quick Backup to all your media files

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