Secret Menus
EDIT: ROOT NOT NEEDED FOR THIS TO WORK.
This is a list of the codes to get into the secret menus on the SF. The list has been complied mostly by egg_head over at XDA, as well as a few others.
I shouldn't have to say it, but I will..
I nor this forum or the op is not responsible if you brick your phone.
Play with these things at your own risk.
Even if I said it's been tested by me and confirmed to work.
It's not my fault if your phone takes a crap on you.
Make a backup of your phone.
Some members of another forum where having trouble using these codes and I've discovered that you need Hidden menu enabled. To enable Hidden menu, do the following:
Go into the Dialer and enter *#83786633 then press the Home key
Go back into the phone dialer and enter *#22745927
Now a box will come up asking for the SPC code. Enter 000000
Press the Hidden menu Enable radio button.
Now you can use these codes.
The dialing code string you have to use is *##
Here are some things you can gain access to
Audio Tuning
*#28346#
Several audio tuning menus.
I've only tested the two items below:
To silence boot and shutdown audio go to Situation/BOOTSOUND and turn the values to 0. I've tested and confirmed this works.
To silence the volume key audio when turning the volume up/down go to Situation/VOLUMEKEY and turn the values to 0. I've tested and confirmed this works.
Full Bat Popup
*#3844228#
This allows you to disable the full battery pop-up.
I have tested this and it works successfully.
HwCodec
*#0002*28346#
Audio path volume controls. Most importantly, it looks like there's a sidetone adjustment.
I have not tested any of these items yet.
Shutdown
*#7594#
This enables you to shut your phone off by long-pressing the power/lock key.
No more pop-up confirmation.
I have tested this and it works successfully.
I also need to point out that this disables your slide lock screen.
Diag/Testing Mode
*#4636*1111#
GPSSetup menu
*#1472365#
The settings are set to the "fixed" values by default.
You can go into Command and then start GPS and force a satellite lock.
There's other cool info there too.
*#7594#
If your enable this, it appears to not only shutdown your phone with a long press of the power key, but it also disables your lock screen (puzzle/glass screen).
Enter GPS debug/settings application by typing *#1472365#
click "Setup" tab
click "position mode"
Click "starting mode
Enable "Cold Start"
Back out.
Other Codes (thanks Dlwicksel!):
*#1472365# - GpsSetup
Very useful tests for the GPS!!!
Setup/Position Mode/ Operation Mode: (Standalone/MSAssisted/MSBased) Starting Mode: (Cold Start/Warm Start/Hot Start) Session Type: (Single Fix/Navigation) Setup/Command allows you to test the GPS and look at the results

Updated above info. Wherever instructed to enter an SPC code, dial 000000. The differs from Sprint customers who have to enter an MSL code, which they typically don't have.
The code to change the voice codec EVRC to EVRC-B has been found. Just follow the directions below. If it dials the code you entered then you need to follow the steps in the first post to enable the secret menus.
Open the dialer then press
**772
SPC code 000000
The bottom of the screen will have buttons that are directional like a d-pad.
Press down until you see:
SVC Mode NAM1
End of BASIC NAM
Exit
Press right once you will see EXIT change to MORE
Hit enter
Press Down once and you will See
HomePage VoiceSO
EVRC
Push right button to change to EVRC-B
Hit OK Phone will reboot
I made a few calls after this and was told by everyone that the quality was so much better.
WARNING!!!!
THIS COMMAND
"##GPSCLRX# - Reset the GPS - (Verizon customers: whenever prompted for SPC enter 000000)"
FORCES THE SAMSUNG MOMENT TO LOOP RESTART FOR APPROXIMATELY 5 MINUTES UNTIL IT FINALLY REBOOTS THE PHONE.
I HAVE TESTED THIS, AND WENT TO SPRINT STORE, WHERE THEY JUST REPLACED THE PHONE
I'm not sure what it would do with the fascinate...
I have used the hidden gps menu alot, but when i tried the "##GPSCLRX# command it made the Samsung loop restart, it would reboot itself for 5 or 10 minutes before finally booting to home screen
I read on another forum (don't remember which one) that it clears the GPS then functions as i said above, the posters fix was to boot to recovery and restore phone to factory defaults.
i was unable to boot to recovery using his key sequence (volume down, power key and camera simultaneously)
I want use the secret menus, but am having issues with the first steps. I am supposed to go into the Dialer and enter *#83786633 then home, then after entering *#22745927 do I do something else bc nothing cues me to enter SPC code??
Thanks!
Here is what you do. You enter the first code, then go home. Back to the dialer and delete the first code then enter the second. after that a screen pops up asking for the password or whatever it is then enter 000000. after that start entering whatever codes you want. It confused me too at first.
On android 2.2, there is listing for mms provisioning in ##DATA#. It asks for the lock code. I tried the SPC but it does not work. I also tried other possible lock codes. What could be the lock code?
##DATA#
MMS provisioning Lock Code = 500667
Hey guys, the hidden menues don't really work after 2.2. I remembered that TSM parts in the COMRom had it already accessable though.
You can also read this link. I have not verified it yet but looks to take care of your full battery pop up issue.

Disable Lock Screen
Hey I was wondering if you were able to get this to work...I upgraded the software the other morning and now no app bypasses the lock screen...I use NoLED as well, and if I can get the lock disabled and be able to use NoLED I would be golden, for some reason that whole lock thing just pisses me off ;o)
I went to the dialer punched in the codes to unhide the menu, I assume all I have to do is hit send? Didnt work... am I missing something?

Use at your own risk and backup your phone first, then you can try the below which worked for me.
To disable it without using an app or rooting your phone, you can enable the Hidden menu by doing the following:
Go into the Phone dialer and enter *#83786633
Press the Home key
Go back into the phone dialer and remove the previous numbers
Enter *#22745927
A menu box will prompt for the SPC code. Enter: 000000
Press the Hidden Menu Enable radio button.
Now you can use the below codes to do the following:
Disable Full Bat Popup:
*#3844228#
This allows you to disable the full battery pop-up.
Enable quick Shutdown and disable swipe screen:
*#7594#
Disables your slide lock screen completely.
This enables you to shut your phone off by long-pressing the power/lock key.
By-passing the pop-up confirmation and mode selection.
Again, do so at your own risk... Done this twice successfully on 2 separate Fascinate phones.
Why? There are threads and websites and blogs listing this stuff already. Pointless post.

I usually don't say anything against ANYONE, but if you google this stuff you will find out that... this is the same post as many others, and I mean identicle.. as in copy and pasted from there to here.
I wanted to try this out for the gps, however its not working for me. Does this work for CM7 or just TW? I cant seem to access hidden menus.
I can only access *#*#4636#*#*, no others?
I can only access *#*#4636#*#*, no others?
You have hit *#22745927 then enter 000000 in the SPC code to enable the hidden menu's
I gather the codes up and put them in one thread I thought might make it easier on the ones looking for them if you got a problem with don't open the thread!!!!
No dice on any key combo I've tried. I found in another forum for different phone that cm7 doesn't work with these codes.

This may be really stupid, but I see that the phone is set to GSM/CDMA auto (PRL).
Does this mean that this thing may work with say Sprint's CDMA network, if I plug in a Sprint SIM?
I read somewhere that the radio supports both GSM and CDMA (although it doesn't mean it has an antenna for both).
I don't think so that chip is 'dual'.
(and there is no list for this options)

Hm, when I enter the service menu as posted above, I get a whole bunch of options, some say CDMA Only, some GSM only. Mine is set at GSM/CDMA auto (PRL).
For a brief description of the menus, see this:

This specific menu does not work with this phone.
Hell yes!
After a few hours trying to uncover the dialing code string for the Fascinate, I finally figured it out!
I've dug into *almost* all the AndroidManifest.xmls to compose a list of hidden menus you can gain access to.
I shouldn't have to say it, but I will..
I'm not responsible if you brick your phone.
Play with these things at your own risk.
Even if I said it's been tested by me and confirmed to work.
It's not my fault if your phone takes a crap on you.
Make a backup of your phone.
I will be doing some more testing and will uncover more hidden menus, but this is what I have for now..
Some members of another forum where having trouble using these codes and I've discovered that you need Hiddenmenu enabled. To enable Hiddenmenu, do the following:
Go into the Dialer and enter *#83786633 then press the Home key
Go back into the phone dialer and enter *#22745927
Now a box will come up asking for the SPC code. Enter 000000
Press the Hiddenmenu Enable radio button.
Now you can use these codes.
The dialing code string you have to use is *##
Here are some things you can gain access to
Audio Tuning
*#28346#
Several audio tuning menus.
I've only tested the two items below:
To silence boot and shutdown audio go to Situation/BOOTSOUND and turn the values to 0. I've tested and confirmed this works.
To silence the volume key audio when turning the volume up/down go to Situation/VOLUMEKEY and turn the values to 0. I've tested and confirmed this works.
Full Bat Popup
*#3844228#
This allows you to disable the full battery pop-up.
I have tested this and it works successfully.
HwCodec
*#0002*28346#
Audio path volume controls. Most importantly, it looks like there's a sidetone adjustment.
I have not tested any of these items yet.
Shutdown
*#7594#
This enables you to shut your phone off by long-pressing the power/lock key.
No more pop-up confirmation.
I have tested this and it works successfully.
I also need to point out that this disables your slide lock screen.

Does this allow us to change intricate GPS settings, ala the "GPS fixes" for the earlier Galaxy S models?

You can gain access to a GPSSetup menu using this short code-

You don't need to change anything.
You can go into Command and then start GPS and force a satellite lock.

It looks like the message goes away, but the screen still turns on when the battery is full. I love how bright the screen is, but even at the lowest setting this phone can light up an entire room.
Thank you SO much for including the "disable battery full popup". That thing was annoying as HELL!
Bummer that it turns on the screen, still. Also, I agree that the screen is extremely bright, even with "night mode" in the Desk Cradle app. I'd like it if I could decrease the "minimum brightness" value even more, so I could use this phone + cradle as my alarm clock replacement.

Doesn't work on DL30. The hidden menu will enable but the audio and disable full Bat menus will not show up. The codes probably got changed for DL30.
The last time the codes worked for me was DI01, the changes I made wouldn't stick on 05/09.
Haven't seen if anyone has found the new menu codes for DL30.

I was able to find the MSL without calling or using the MSL app.
I did an alteration to the following instructions, and was able to retrieve it after a couple attempts.
http://androidforums.com/htc-hero-sprint/117401-guide-easy-way-get-msl-without-calling-sprint-using-cmda-workshop.html
and the following thread http://forum.xda-developers.com/showthread.php?t=689470 thanks kyouko
I tweaked the instruction a little bit by presenting the msl input screen and exiting before returning to alogcat.
Instructions I used:
Fresh boot phone and await all apps/things (scripts, widgets, and misc) to load.
Launch alogcat
Clear out the log by pressing menu button and then select "clear"
Go to your dialer and enter ##DATA# or ##3282# which will bring up the DATA menu
Once the menu pops up just select "View" mode
At this point you will see a screen with 6 selections. Select "others".
Then select "work mode".
Attempt to input a random msl code. I used "000000". Of course it is incorrect. I then clicked cancel and then returned to the previous menu (work mode).
From here either press and hold the Home Key and select aLogcat if you ran it before, go to your tray and run Logcat.
After opening Logcat it will update, once it finishes press "Menu" and "Pause" the log.
Then scroll until you see a group of entries labeled "I/MSL_Checker" which should be green.
Locate the line that has "MSL result : " at the end of it (Or press Menu and Filter "MSL" )
And there you have it, your 6-digit MSL code without ever calling sprint or using a computer.
Again thanks kyouko for your instructions.
You can grab it right from the shell, getprop will list it (ril.MSL).
If you have busybox installed just getprop | grep -i ril.MSL
If busybox is not installed just getprop ril.MSL - it should be the number listed directly under. Or a simple getprop and scroll through the entire list.
The more options/choices, the merrier.
Me i use a combo of QXDM and CDMA WS. Yeah more complex, but ties into other stuff i use them for.
kyouko.. been a long time since i saw that username :O

Does the dialer codes work in CM7?
Here is a brief history of what I tried to get my AT&T NOTE 3 to get unlock without unlock code which ended up screwing up my phone.
I rooted. Attempted Region Unlock by ChainFire so my Tmobile sim would work; didn't work. Found some leads for hidden dial pad menus. The one with the most accesibility and confusion was the "Access the dial pad and type the following: *#197328640#." this one is tricky. You need to first hit menu then select "back". There will be no changes in the screen. then you hit menu, key entry "Q". again you will see no changes. Last you hit menu, key entry "0000". WAIT MANY SECONDS. You will be taken to another menu.
I made many changes. Thing is, I've been around the many communities and know my way around the wierd codes in the hidden menu. Do not mess with anything in there! It is what got me to screw up my SIM reader. I resorted to an option in the hidden menu where you go from "UE SETTINGS AND PROTOCOL" to "SETTINGS".... there were a few other options which led me to NV REBUILD. The NV from my experience in the RAZR M SIM unlock allows the SIM unlock. If it were to be rebuild it would reset the changes I've made. It rebuilt and I rebooted my phone and I immediately received 4G and was able to make phone calls and texts.
