None of the buttons working, and there is a blue box around task bar
I took a screenshot, and now I can't use any of the buttons (including the soft buttons), and there is a blue box around the task bar. I can't shut it off, pull down the task bar, or receive calls or texts. I CAN take a screenshot, and scroll on the screen. It's stuck on the web browser.
EDIT: I still have no idea what that was, but I was able to hard shut off, and it works now!
