My theory is they always get buggy as new ones are released. They get better a few months later.

That said I’m planning to get a mini and there was another thread where someone reviewed one. There seems to be some touch screen issues when in a case with a screen protector they say can be fixed with software based on reviews. I usually wait at least two software pushes after release to buy.

ETA looks like they fixed this one https://screenrant.com/...n-fix-ios-14-update/
