I went to the Apple Store today because of my switches being loose and clacky. The Genius replaced it but the issues were still there but wouldn't budge on swapping it again. He did mention that I was getting a brand new iPhone, serial number started with 7U and he mentioned that this was with the proximity sensor fix! I said that I heard it was software related and he said no and that Apple had done a hardware fix. Pretty trippy! People grab your pitchforks! I don't know how I can validate the claim other than maybe canning my receipt? But it is 2AM here so I'll scan later. Anyone else know that the prox sensor is a hardware fix?
