I've been debating returning/swapping my iPhone because it has been a lot of trouble. OK, we all know about the issue with the death grip. I definitely have it because I can stop a download in progress in iTunes by putting my finger in that spot. Since it stops and starts within 2 seconds of me doing that, I know I'm one of the affected ones. But more troubling as time goes on is the proximity sensor. I was talking to my boss as he was out and about and all of a sudden FaceTime got activated. Later, I stopped hearing my mom because the Hold button had been hit. I owned an iPhone for a bit over a year and an iPhone 3GS for a year. I never had any of these problems. I think I want to just try to switch phones, but eventually I may give up and get a 3GS and swap it out with my mom, who has my 32GB 3GS now. I do love the retina display, but this is getting to be crazy at times.
