Techno cheat.. 9jakingmusic

Hi,
Today Let me discuss about some secret
codes that we developer and android users
are not knowing mostly but it can be helpful
to us in some way. Around 2 days ago, i got
one article describing iPhone secret codes
those i have posted here: http://
fb.me/16v9zEEdK . So i thought same as
iPhone secret codes there must be having the
same kind of secret codes for the Android as
well. After searching and doing google, i got
many secret codes.
Note: This codes are not founded by me, i
have just collected through search and sorted
it out.
1. ##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
2. ##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.
3. 27673855#
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.
4. ##34971539#*#*
This code is used to get information
about phone camera. It shows following
4 menus:

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.
5. ##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

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.
