Okay so I finally got around to checking this out. (I have a 6 month old son) anyways I was able to turn off the shutter sound.
I did so by using TKFileExplorer same app used to install apps onto the phone.
I went into Registry
then uploaded camsettings.ini to the computer from the phone
then I opened the file with notepad
In the file there is (ShutterSound=1)
the sounds are
these are the settings to make the stock shutters sounds 0=1, 1=2, and 2=3
so I changed the number to 3 which doesnt have a sound and saved the file
so the file should appear as so (see attached pics)
Then you just delete the old camsetting.ini that is on the phone(you might want to make a back up file just in case)
and upload the one you just adjusted for no shutter sound
The settings in camera will now show nothing in the shutter sound spot it will just be blank.
I do still get a beep when the auto focus lets you know its ready but its way better then the loud sound that wakes my child up when I'm trying to take pictures while he is sleeping!
Also the video start sound is gone but the video end sound is still there
