The last iphone that i used a clear case was iphone 7 after using for a year noticed several scraches ot the back aluminum body due to dust that trapped inside the case , since them started to use Apple cases (leather and silicone) and maybe because those cases has some microfiber protection inside never had any problem with scratches... now im planning to go back to clear cases what is the situation with those cases now ? they can still hold dust inside and scratches the phone like before? And what is the best clear case for 12 Pro Max?
