Android – Secret codes

By -

Hi,

Today Let me discuss about some secret codes that we developer and android users are not knowing mostly but it can be helpful to us in some way. Around 2 days ago, i got one article describing iPhone secret codes those i have posted here: http://fb.me/16v9zEEdK. So i thought same as iPhone secret codes there must be having the same kind of secret codes for the Android as well. After searching and doing google, i got many secret codes.

Note: This codes are not founded by me, i have just collected through search and sorted it out.

1. *#*#4636#*#*

This code can be used to get some interesting information about your phone and battery. It shows following 4 menus on screen:

  • Phone information
  • Battery information
  • Battery history
  • Usage statistics
2. *#*#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.

3. *2767*3855#

Think before you give this code. 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 give 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.

4. *#*#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 camera firmware version
  • 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.
5. *#*#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.

6. *#*#197328640#*#*

This code can be used to enter into Service mode. You can run various tests and change settings in the service mode

7. WLAN, GPS and Bluetooth Test Codes:

*#*#232338#*#* - Shows WiFi MAC address

8. *#*#8255#*#* => This code can be used to launch GTalk Service Monitor.

9. Codes to get Firmware version information:

*#*#4986*2650468#*#* - PDA, Phone, H/W, RFCallDate

*#*#2664#*#* - Touch screen test

*#*#0588#*#* - Proximity sensor test

11. To get to a File copy screen for backing up your images, videos, voice memos, and other media files, type in *#*#273283*255*663282*#*#*

12. If you want to change default actions for the End Call and Power button, punch in *#*#7594#*#* and change those settings.

13. Android also supports the Service Mode, invoked with the *#*#197328640#*#*code, that lets you run tests related to the WiFi, Bluetooth, and GPS circuitry. Other factory tests include LCD (*#*#0*#*#*), vibration and backlight (*#*#0842#*#*), touchscreen (*#*#2664#*#*), RAM (*#*#3264#*#*), proximity sensor (*#*#0588#*#*), and more.
