One of the most popular practices amongst software developers is to leave ‘backdoors’ within the code, which essentially allow anyone with knowledge to get into the system at a much deeper level than you’d expect from an end-user. These backdoors aren’t always with a malicious intent; most of the time, they allow the OEM or programmer to get into the system for troubleshooting when other, usual modes of access have been blocked. They can be quite friendly and helpful if you know what you’re doing.
Smartphones have a good share of these as well, where they’re generally known as secret codes. Most of the time, these numeric/symbolic sequences allow you to access hidden menus, diagnostic tests, areas that could change some of the most basic parameters of your device and whatnot. These secret codes, in fact, have not been exclusive to smartphones, but have long been a part of the dumb-phones and then the feature-phones before most major OEMs joined the smartphone bandwagon. For those devices that run Android, certain codes are shared across the board, and hence, can be used on a variety of devices.
What follows is a collection of some of the secret codes common to the Android platform. All of these would be entered through the phone dialer (just punch in the sequence as shown). Since most hidden menus are manufacturer specific, there’s no guarantee that they’ll work across all Android smartphones, but you can try them out nevertheless on your Samsung, HTC, Motorola, Sony and other devices. Be advised, though, that some of these can cause serious changes to your device’s configuration, so don’t play with something that you don’t fully understand.

your welcome..
thanks for sharing, but on JB 4.1.2 many of these codes are removed from samsung, f.e. the *2767*3855# hard reset code, as it has been prooved that it could be executed via a malicious browser website...

Actually, some still work, but our phone uses the old format instead of the new. So don't type "*#*#1234#*#*", but "*#1234#". Same for service mode: "*#197328640#". Etc. Also interesting: "*#9900#" for "SysDump" and fast dormancy.

Hi all, full testing hardware

Looking for the dialer code to enter into calculator to access hidden menu on a Sprint Galaxy tab2, I believe it is a long string of letter and symbols it ends in "+" sign. Just can't find my notes, the standard ##3282# or ##3424# do not work.Thanks
This is great, thanks, although I don't know what half of them mean
The Secret Codes are working ... :laugh:
Very Thanks Bro... :good:

I want my Jam not to ask me Pin code at start up, how can i do this ? Any program or settings u know ? I will use this function in phonealarm , when switching the flight mode profile to normal radio mode profile ( yes it can do this according to the daily schedule u made )
Hello
Go to menu phone in start menu or settings-->make sure that the checkbox on the separator phone saying:require a Pin when phone is used is off!!that's it!
Cheers
Thanx a lot Dervian, that was i needed.
I have a Touch 2 and ported my old telephone number when switching mobile providers. The phone still shows the old number in a few places such as SIM Manager, and in Settings>Personal> Phone.
Where is the number held, and how can I change it?
Thanks
Kevin
I think you might have to reset your phone and/or remove the sim temporarily. But i've only had experience with non phone versions of Windows. Someone else may be able to give you a better answer.
try open sim manager and go in menu->tools-> list your number (menu tools is not visible without gesture from down to up). In this menu you can change number
Hello everybody,
Like many others here I had problem with GPS on my device. (unable to get a lock)
So I began searching for a solution which does not involve rooting.
And I cam across a solution somewhere on internet.
I will post it here for you people!(Please note down the default settings in case you want to revert back).
From your phone dialer type *#*#1472365#*#*- This will bring up the secret GPSSetup2 application.
Settings\Parameter Settings\Address\Server Type: 1x MPC
Settings\Parameter Settings\Position mode: option3
Settings\Fix Request Settings\Session Operation: Standalone
Settings\Fix Request Settings\Server Option: Local
gpsOne XTRA\Xtra Enable: Enable
After the following steps: Save the settings by exiting and then turn off and on your phone.
After this: use*#*#1472365#*#* and again enter GPSSetup2 application.
Enter: Commands/TTFF test and press start test. It will run the test 5 times. Exit the application.
And after this you will get gps lock in a few seconds. I get it under 10seconds.
Please Note: I live in India, and I do not know the following setting applies for outside India users too.
Thanks.
I am using Galaxy 3, 2.1 update 1 unrooted.
PS: Please run the TTFF test under clear sky for faster response time.
Just used this fix on tmobile galaxy apollo in the uk and it worked well.
Sent from my GT-I9000 using XDA App
Dont work for me :-( but i have froyo..
Sent from my GT-I5800 using XDA App
i hav a better solution.. if ur g3 boots with gps off,it may not work.. but it wil work if u boot ur g3 with gps on..
cheers..
thanks a ton for this tip. now I get lock in around 1 min. (i5800 - 2.1).
Now I can use my GPS!
gps in jpf2.2 works well under
to 2.2 froyo users setting this parameters
in phone dialer insert this code *#*#3214789650#*#*
Settings\Parameter Settings\Position mode: option3 default: option2
Settings\Fix Request Settings\Session Operation: Standalone default: MS based
Settings\Fix Request Settings\Server Option: Local default: Default
gpsOne XTRA\Xtra Enable: Enable default: Disable
in "Commands" press “Get position” select "Log GPS info to SD card" and press "Start GPS" wait locate longitude and latitude and press "stop test".
Exit the application

Has anyone tried the following:
*#810# ?.
The above seem to have some functions on the R7Plusf ... it sent me back to the Original setup screen ! Phone asked me for language preference ... then Google Account name ... and it would not accept my original account name - saying that already exists on the phone. A reboot did not kill the mode. Finally I managed to Kill "Engineer Mode" process that was running and got back into my phone. All the folders and arrangements are gone in the default launcher. However all the data, call records, SMS etc. are intact. That's it - I am not fooling around with these codes any more!
Thank you so much for the codes!

How did you manage to kill "Engineer Mode" process? I am in the same situation but with Oppo F1f...
Its the same as the Z2: *#*#7378423#*#*
Other codes for various settings should also work:

(similar for 4636 and "info")
