This is getting ridiculous, and I'm pretty sure at this point, the Apple store guys are starting to not believe my hand is causing this. I hold my phone in my right hand, and this is somehow causing the bumper to deteriorate extraordinarily quickly. I do not wear any jewelry. Here is my two week old replacement bumper: And here is the other side for comparison: As you can see, only the side I hold deteriorates, while the other side remains perfect, so I know it's not the material of my pants doing the damage. The side that is deteriorating has relatively large chunks of rubber missing, is becoming "wavy," and even the plastic is unevenly "chipping away" it seems. I have yet to drop the phone or bumper, an I have never washed or boiled it. I wouldn't be posting this thread if I didn't stupidly hand over $29 plus tax for it. Is anyone else experiencing this problem to this extent, this quickly?
