Android Mobile Secret Code

Take a look into the secret codes given below,

*#*#4636#*#* Displays four menus on your screen with cool information. Those menus are,
1. Usage statistics.
2. Battery information,
3. Battery history and
4. Phone information,
Directions for using the above code: I believe these go in the dialer BUT be aware when you dial the first *# you may notice the * becomes the #. So if you dial *#*#4636*#*# you will see #*#4636*#*# (Notice the first * missing) You need to dial *# then delete the # and start again and this allows the first * to stay in place.

*2767*3855#
