Q: iPad mini 4 screen is buggy. Drawing straight line, the line is choppy.

A bit hard to explain. I was playing a game and noticed the moment wasn't consistent. Id stop and start like it was choppy. So I pulled up notepad sketch and drew lines with my finger. The line was choppy, like this...   _____ __    ______ _______ So that tells me the touch screen is choppy and buggy.

I Restarted and it was fixed for a bit but then started again. Now the touch is very buggy, getting Worse. Anything to do or just go to the Apple Store? Mini 4, latest iOS.
