It's motion sickness and this is a common complaint with this new OS they have. lol
Fix it like this:
You can make your phone less jittery by going to ?Settings,? then ?General? and then ?Accessibility.? Click on ?Reduce Motion? to turn it on. This should cut back on some of the movements that are can trigger nausea and dizziness.
That should help - my daughter had to do this too - so it isn't an old thing, dear.
