The silicone cases are trash—my iPhone 12 was in perfect condition when I turned it into Apple for credit except for some dings and chips on the bottom corners where all of the (three I think) Apple-branded silicone cases chunked away every time I would drop the device until the phone itself was damaged. I’m not that klutzy nor do I drop my phone that often but hey **** happens and as a non-driver I do walk a lot, making the occasional accident more likely.
Although they aren’t as pretty or as nice to the touch I’ve been sticking with the clear, hard plastic Apple MagSafe cases and other than some impact-borne cracking they do tend to hold up much better in my experience.
I don’t do the leather cases because of potential water damage and how ugly the fake “patina” (usually just filth and grime buildup) is on cheap-quality leather.
