Hello, I'm having a small problem with the onscreen keyboard. For some reason it will not play sound when I tap a key. It worked last night, and stopped working this morning. I tried turning on and turning off the sound option under the keyboard settings in the setting menu. i tried turning off the keyboard compleatly and turning it back on and it still does not work. I tested the vibrate function and it turns on and off when I make the changes in the menu. has anyone else had this issue? If so how did you fix it. Thanks for your help!
