I have an Xperia 10 II (or something like that, the slimmest Android device I could find back in early 2021). The back cover is cracked all over, to the point I sometimes get cuts on my fingers. Two of the corners have dents.
The back camera that takes the actual photo is several degrees off (like 10 or 15°) from whatever is used for the preview. Works perfectly in all the other ways. Probably isn't waterproof any more, but I never needed that before, either.
