Android Secret Code

Xybernetics IncA while ago, I called my Service Provider to unlock my phone since I travel a lot (of course they charge me CAD$50 for this service… what a rip off) and I needed to utilize international SIM card. They asked me for a IMEI number which I found out from them there is a “magical” sequence of number you can enter to get it. Of course, this sparked my curiosity. So for this tech talk topic, we’ll reveal several hidden secret codes which can be used in any Google Android mobile phone to access things which are not accessible by default.
These codes have been obtained by decoding various .apk files present in the phone firmware.

Miscellaneous : WARNING
*#*#4636#*#* This code can be used to get some interesting information about your phone and battery. It shows following 5 menus on screen:

  • Phone information
  • Battery information
  • Battery history
  • Usage statistics
  • Wifi information
*#*#7780#*#* This code can be used for a factory data reset. It’ll remove following things:

  • Google account settings stored in your phone
  • System and application data and settings
  • 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.

*2767*3855# This code is used for factory format. It’ll remove all files and settings including the internal memory storage. It’ll also reinstall the phone firmware.
PS:
Once you issue this code, there is no way to cancel the operation unless you remove the battery from the phone. So think twice before giving this code.
*#*#34971539#*#* This code is used to get information about phone camera. It shows following 4 menus.

  • Update camera firmware in image (Don’t try this option)
  • Update camera firmware in SD card

  • Get firmware update count

WARNING:
Never use the first option otherwise your phone camera will stop working and you’ll need to take your phone to service center to reinstall camera firmware.

*#*#7594#*#* This one is my favorite one. This code can be used to change the “End Call / Power” button action in your phone. Be default, if you long press the button, it shows a screen asking you to select any option from Silent mode, Airplane mode and Power off.
You can change this action using this code. You can enable direct power off on this button so you don’t need to waste your time in selecting the option.
