HELPFUL INFORMATION FOR ALL ANDROID
USERS
You need to study the application of the
code before applying it as the only way to
stop it from processing is to remove the
battery from the phone
Do you have an Android phone or Tablet?
Do you want to or 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 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.
––> Test Service Mode
*#*#197328640#*#*
This code can be used to enter into Service
mode.

settings in
the service mode.
