Any time I'm in a phone call, and I need to press a number into the keypad, it won't toggle it up.......the keypad is inaccessible. I have no idea what the issue is at present but that's not acceptable. I can press the keypad button and it lights up green when touched and the arrow indicating whether the keypad is up or down changes with each touch, but no keypad. When I hit Phone from home, I can toggle it, no problem....just not during a call. Anyone else have/had this problem yet?
