My granddaughter was playing games on my Galaxy Tab S 10.5 and the screen is locked on a game. I can move around the game but I can't get back to the home screen. None of the buttons work, not the home or back or recent apps keys work. Help!
Welcome to Android Central! If you can't bring up a menu for the game, just press and hold the Power button for about 15 seconds. This should force a power off. Then turn the tablet back on again.
