Android - Do you know other Android keypad commands (dialer codes)?
This page has a good listing of keypad commands.
Here is the post:
*#*#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
*#*#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#
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.
*#*#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.
*#*#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.
*#*#273283*255*663282*#*#*
This code opens a File copy screen where you can backup your media files e.g. Images, Sound, Video and Voice memo.
*#*#197328640#*#*
This code can be used to enter into Service mode. You can run various tests and change settings in the service mode.
WLAN, GPS and Bluetooth Test Codes:
*#*#232339#*#* OR *#*#526#*#* OR *#*#528#*#* - WLAN test (Use "Menu" button to start various tests)
*#*#232338#*#* - Shows WiFi MAC address
*#*#1472365#*#* - GPS test
*#*#1575#*#* - Another GPS test
*#*#232331#*#* - Bluetooth test
*#*#232337#*# - Shows Bluetooth device address
*#*#8255#*#*
This code can be used to launch GTalk Service Monitor.

*#*#1234#*#* - PDA and Phone
*#*#1111#*#* - FTA SW Version

Codes to launch various Factory Tests:

*#*#2663#*#* - Touch screen version
*#*#2664#*#* - Touch screen test
*#*#0588#*#* - Proximity sensor test
*#*#3264#*#* - RAM version
Here are the standard vanilla codes that should work across all devices:
A quick grep through the source code revealed these secret dial codes (for Android 4.1):
- 4636 (show debug info in apps/Settings)
- 8351, 8350 (start/stop voice call debug logging or so in apps/VoiceDialer)
- 36245 (debug email in apps/Email)
- 8477 (? in apps/Protips)
- 225 (debug calendar in providers/CalendarProvider)
I did also check all available Google Apps from http://goo.im/gapps (Versions 2.2-4.2 w/o 3.x):
Android 2.2 and 2.3:
- 8255 (Google Talk)
- 46, 7867, 2432546 (GoogleServicesFramework)
Android 4.0, 4.1 and 4.2 Jelly Bean:
- 8255, 46, 7867, 947322243, 2432546 (GoogleServicesFramework)
- 759 (GooglePartnerSetup)
Note:
This functionality is realized via regular broadcast intents and filters, i.e. any app that wants to can define their own code and subscribe to those broadcasts. Also note, that the above code are only the visible open sourced part (CyanogenMod here), and Google Apps (which I did unpack and then scan). If you're interested in doing it yourself, unpack them with apktool and grep through their AndroidManifest.xml files for this way):
egrep -r --include=\*xml SECRET_CODE\|android:host=\"\[0-9\] .
It will find occurences in AndroidManifest.xml:
<receiver android:name=".checkin.CheckinService$SecretCodeReceiver"> <intent-filter> <action android:name="android.provider.Telephony.SECRET_CODE" /> <data android:scheme="android_secret_code" android:host="2432546" /> </intent-filter>
There is an app on Google Play that will inspect the AndroidManifest.xml files of all the apps installed on your phone for secret code broadcast receivers, and then list the codes associated with them.
The app is called Secret Codes Revealer and you can download it from Google Play.
(Note: If you get a blank entry in the list, it is because the app hasn't hard coded the secret code and allows you to change it)
