The screen on my iPhone SE 2nd gen stopped responding to touch.

My 2nd generation SE screen stopped responding to touch and I don't know what to do. I am unable to power it off and I have already tried to reset it by pressing volume up, volume down, and then holding the power button. It reset but my screen still doesn't work. Currently I am waiting for the battery to die in hopes that when I charge it again, it will work. Any suggestions?
