iPhone Xr/Xs/Max - all have protruding camera. If you don't use a casing at all and you often pick up the phone and put it back on the flat table, the phone would sometimes move a bit here there on the table because my workbook bump the phone - question is: will the camera lens eventually get scratch, scuffs, not crystal clear anymore due to friction with the table surface? It's like the lens is rubbing the table. Let me know your thought, I personally don't like case.
