I think I'm giving up after 4 iPhone 6 64GB space gray models. I'm tired of the lack of QC. First one exchanged for dark upper screen where the battery icon is. Replacement had a loose home button and the screen click over the volume buttons. Screen was ok. Returned and waited almost 2 months. Tried again. Third was ordered from ATT. Perfect screen, but again a loose home button, crooked mute switch and a ding in the metal by the headset jack. Hung on to it for 2 weeks, but ended up returning it too. Just tried again yesterday at the local Apple Store. Out of the box it had a dark upper screen, loose home button and it was bent/bowed. If you laid it screen down on a flat surface you could slide a business card under it without touching. First bent iPhone I'd seen in person. They tried to exchange it but because I used Next they couldn't get the upgrade eligibility reset. So I took a refund and left. Pretty disappointed overall. Over half the display iPhone 6s had darker upper screens there. So I was worried going in. The 6+s looked better. May be time to move on to something else. Bummer.
