Like it wiggles while you use it?

I would make an appointment at your local apple store o authorized service provider because it shouldn’t be doing that.

You’re welcome! 👋🏼😉

There is possibly something wrong with the screen, so I’d back it up, keep it backed up and get service at your earliest opportunity.
