TLDR: a cheap case is higher quality in my experience.
I had a few for my 11 pro max and they were $50 and lasted a year. Only after I bought my 14 pro max the sides were peeling off of the back plastic piece.
I tried two different otterbox cases( symmetry and commuter) and the quality isn’t great anymore.
The two cases I love are the Apple silicone case and the Sonix case.
Maybe the monster under your bed is trying to open the apps while you sleep /s
You have to press and hold the Digital Crown to get to the apps. Unless you’re pressing your arm against something that touches the crown nothing will happen.
