It appears that some debris (?) is getting trapped between the Belkin acrylic case and my iPhone, and is leaving marks on the aluminum and plastic back cover, as well as the stainless steel screen bezel. The iPhone is a bit loose in the case, so maybe that’s the problem!
Before you think that I’m being careless:
– I always put my devices in cases (either acrylic or silicone) to protect them
– I always put my devices alone in my pockets (no coins, keys or other items)
– Even cheap (eBay special) acrylic cases have never scratched any of my devices before
– My pockets are clean of debris
I’ve contacted Apple and Belkin… I’ll keep you posted!
First update: Others are reporting the same problem – see the comments below.
Second update: AT&T refused to refund the Belkin acrylic case and to exchange my iPhone, despite selling me both…
Third update: Belkin agreed to give me a refund for the Belkin acrylic case and to cover the cost of exchanging my iPhone (10% restocking fee)!
Fourth update: My iPhone was exchanged for free :)
