What special phone numbers can be used to display (hidden) info on Android phones? Possible Duplicate:
  Do you know other Android keypad commands ?  




In another post someone mentioned the special phone number #*#4636#*# to list CPU specific information.

I would like to ask you to list such special phone numbers in this post.

Mind you, I am not looking for a list on a web page (I'm sure that such a list is available somewhere). 

I am looking for special numbers you actually used yourself, so you can vouch for the fact that they actually work.

Please mention your phone, because I can imagine some of them are phone specific, no ?
I'm running 2.1 Eclair on a Samsung Spica.

Well... the universal *#06# will display your IMEI - always a good idea to store this in a safe offline place in case your device is misplaced / stolen.

*#*#7780#*#*


will take you a screen where you can Factory Reset your device - you need to press an additional button to confirm or BACK to exit.


  *#*#7594#*#*


will show you Shutdown App configuration - you can choose to have the device power off directly instead of showing the menu for Airplane Mode / Power Off etc. when you long-press the power button. There's also an option for keeping the LCD on during the duration of a call - also useful to some people!


  *#*#197328640#*#*


shows a SERVICE MENU where different diagnostics can be carried out.


  *#*#526#*#* OR *#*#528#*#*


takes you to a WLAN test screen where you can check Transmit (TX) and Receive (RX) capabilities - press MENU for options.


  *#*#0*#*#* 


LCD test


  *#*#0842#*#*


Vibration test

Naturally, some of these may be specific to certain device models only.
