My 6 Plus has a spot in the rear camera. It shows up in the camera app and photos, in the same place. It's more obvious in lighter backgrounds. I've attached a couple of pictures. I currently do not have an Apple Store near me. Apple phone support diagnosed the issue and said it was hardware related. I opted to send it in for repair under warranty. My questions are: Do they repair my phone or replace my phone? If they replace, will the new phone be unlocked? My phone is in pristine condition, unlocked and currently this is the only issue it's experiencing. I would just prefer a repair. Any real world experiences would be greatly appreciated. Thank you!
