Re: unresponsive lock screen samsung galaxy s4

I don't have a solution, but I've been having the same problem. Previously, when I tried to turn the screen on, the bottom buttons would light up, but the screen would remain black and unresponsive. Now I have the same issue you do; when I push the lock button, the screen comes on, but is unresponsive; no unlock animation, and no way to touch restart/shut down.
