Secret Hack Codes for Android Mobile Phones

Hello Friends, today i am going to share several
secret codes for Android Mobile Phones . These
Android codes will help you to know more about
Android mobiles and help you to explore more
about your Android Phone.
Secret codes are those codes which are usually
hidden from users for any misuse and exploit. As
we all know android is very new platform from
Google for smartphones. I have tested these
codes on my cousins Samsung Galaxy having an
Android OS version 2.2 . I am sure these will work
on all previous versions.

only because of study purpose. This codes may

Complete Information About your Phone

interesting information about your phone and
battery. It shows following 4 menus on screen:

This code can be used for a factory data reset .
It'll remove following things:

5. End Call/Power
*#*#7594#*#*
This one is my favourite one. This code can be
used to change the " End Call / Power " button
