Default Google Android: Hidden Secret Codes

Pretty useful to know!

NOTE: All codes have been checked on Google Android phone Samsung Galaxy I7500 only but they should also work in other Google Android phones.

EDIT: Yes, input them on the phone dialer!


*#*#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.

Codes to get Firmware version information:

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

*#*#1234#*#* - PDA and Phone

*#*#1111#*#* - FTA SW Version

*#*#2222#*#* - FTA HW Version

*#*#44336#*#* - PDA, Phone, CSC, Build Time, Changelist number

Codes to launch various Factory Tests:

*#*#0283#*#* - Packet Loopback

*#*#0*#*#* - LCD test

*#*#0673#*#* OR *#*#0289#*#* - Melody test

*#*#0842#*#* - Device test (Vibration test and BackLight test)

*#*#2663#*#* - Touch screen version

*#*#2664#*#* - Touch screen test

*#*#0588#*#* - Proximity sensor test

*#*#3264#*#* - RAM version

Just in the dialer I think, that's how it normally works.

It would be so much cooler if there was a code allowing you to launch intercontinental ballistic missiles at small countries though...

I believe these go in the dialer BUT be aware when you dial the first *# you may notice the * becomes the #. So if you dial *#*#4636*#*# you will see #*#4636*#*# (Notice the first * missing) You need to dial *# then delete the # and start again and this allows the first * to stay in place.

Hope this helps

Thanks,

Would taking battery out be enough? And would this delete any info about txt messages and phone calls. I need to return the phone to the shop, but if they find i used it they would not take it back. My kid sent a message and tried to phone me when left phone on my desk.

No. You need to do a hard reset to return it to store fresh condition

ETA; sorry, just seen its a Wildfire.

hey, dialling *#*#4636#*#* on my HTC Desire worked fine BUT my attempt to add this command to the list of contacts failed because I was forced to choose the type of phone of this "customer" (mobile. home, ..., Other) and, If I chose Mobile, then calling this customer would dial M *#*# etc and if I chose Home - then H*#*#..., Other - O*#*#... - none of which would be recognized as valid. These letters appear at the moment of pressing the call button, they are not present in the contact's entry. Any suggestions?

I know this is old thread but I am surprised that noone noticed following.
Most of this codes are for Samsung phones and does not work on any other phones.
Also most of this works on any Samsung phone.
For example *2767*3855# work an all samsung phones does not metter which OS it is. It is factory reset even on old phones (for example T100 or A300 or any other Samsung).
