iPad moving by itself
So, I woke up with my iPad behind my pillow like usual. The only difference was, it had no case. Basically, when I turned it on, it had no problems but after a few minutes, it kept on glitching and moving by itself which is annoying and irritating. I kept on shutting it down although I struggled since I couldn’t use my iPad properly while I do so but nothing changed and only kept on glitching and moving. How do I fix this?
