I had set my tablet aside and it was left on for a day. Next day, I picked it up and swiped to enter my password. I can't enter anything in the password field. So I tried swiping for the camera function. After the camera function opens, a few seconds later a message comes up that Samsung Keybord isn't working. Find My Mobile unlock says something went wrong, so won't unlock. Hard reboot with Power and Volume buttons brings up the same problem. I can't enter anything in Password field Any suggestions to fix?
