Just now, I was using my phone and all of a sudden the touchscreen wasn't responding so I locked the phone and was going to unlock it just assuming it was a little glitchy thing. Now the touchscreen won't respond. All the side buttons work but I can't unlock my phone or even shut it off since I need to slide the bar down. Even though the side buttons are responding, they are acting quite slow meaning once I press them, I then have to wait a few second for it to respond. Does anyone have any suggestions as to what I can/should do?
