The stories that I see on this forum about dirt etc. trapping inside 3rd party cases scratching phones has made me use only Apple cases.
I have both the Apple leather and Apple clear case. I prefer the clear case despite the weird a$$ back magsafe design because it is so darn clear and makes my Pacific Blue shine. Yes, i am superficial.
I’ve always used 3rd party cases for all of my iPhones, and never had any issues with dirt and debris scratching my phone. I also can’t justify paying $49-$50 for a case that I would keep switching out for another case because I would get bored of it. For the 12 Pro Max, I did order a silicon case that I sent back the same day I received it because so many people said it’s a lint magnetic. I found a case I like better than the Apple silicon case. It feels almost exactly the same as the Apple silicon case except it’s thinner which is exactly what I was looking for.
