NOTE: If some codes don’t work on your mobile phone, try to use only *# in the start of the code and only #* or only # at the end of the secret code. For example
*#4636#* or *#4636# .
*#*#4636#*#*
This code can be used to get some interesting information about your phone and battery. It shows following 5 menus on screen:

Menus might differ for different mobile phones. Check out following video which shows the above code in action:

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.
