My iPhone 6 had 'spots' of discoloration on the gold tint backing
Surprisingly, when I received my iPhone 6, I was thrilled. It's a great device! However, I did have these weird spots on the gold backing - like the gold tinting process was off or something. Anyhow, no one has ever reported it that I could find. I took the phone into the Apple store, and the manager swapped out my model for 'refurbished one.' The problem with the spots is that in certain lighting you couldn't see them. Due to my OCD, I was not able to ignore it and they stuck out like a sore thumb to me. So, I begrudgingly took the phone in, and the manager said he couldn't 'see' the spots, but the girl that was waiting on me did see them. I think Apple reps get really annoyed at their end users being so OCD over defects. However, I have to say Apple has done a really good job of taking ownership over their hiccups on the assembly line. It's just such a struggle for us 'perfectionists' to except something less than an ideal rendition of the product. I believe if you lay down $750+ for a device - it has to be delivered as such.
