I was reading some topics on XDA Forum when I saw this thread about Universal Samsung/Android secret codes. I’ve listed them below. These secret codes are used to access some hidden menus and configurations on the Android operating system. Well, some of these menus were meant to be hidden because these could alter the system defaults. Modifying some of the settings could cause serious changes to your device’s configuration, so don’t play with something that you don’t fully understand.
Warning: Try at your own risk! Codes take effect or activate automatically upon entering the last character. No confirmation messages are displayed so try the codes only if you know the outcome. Codes for hard reset/factory reset could wipe out all your saved information such as contacts and messages so make sure you have a backup.
To use the codes, just type them in sequence on your phone’s dialer. See the screenshot below.
*#06# – IMEI Number
*#0*# – Enter the service menu on newer phones like Galaxy S III

I’m not sure why but this site is loading extremely slow for me. Is anyone else having this issue or is it a issue on my end? I’ll
check back later on and see if the problem still exists.
Hi Isaac, I think it’s just an issue on your end. 🙂
Thanks to my father who told me on the topic of this webpage,
this website is truly remarkable.
Hi sir i have a jelly bean phone when I am dialing these codes nothing happens why ?
Hi Hermant. The service menu is disabled by default on Android devices running on Jelly Bean. You have to type *#22745927 first and you will get an enable/disable option. Check enable and you’re all set. Here’s the article for that: http://androidforums.com/samsung-galaxy-s3/708404-secret-unlocking-jelly-bean-service-modes-found.html
