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 were unable to enter these menus and I discovered that you need to enable 'Hiddenmenu' to do so.
To enable this menu, do this:
Go into the Dialer and enter *#22745927
A box will come up asking for the SPC code. Enter 000000
Press the Hiddenmenu Enable radio button.
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've also discovered by doing this, it will disable the puzzle/glass unlock screen.
Personally, having to push a button and slide the screen is redundant.
I like the one-step process.
Diag/Testing Mode
*#4636*1111#
