Hi, I have a Samsung Galaxy S3 on VZW. Often when I make a call that requires keypad presses (e.g. for menu selection), I touch the keypad icon, but the keypad goes blank when my finger approaches it, then reappears (after a couple of seconds) when I pull my finger away. I have to hang up and start the call again, hoping that the problem will not reoccur, which it does about half the time. Really aggravating! Is this a bug? Thanks, - bill.
