So, I bought a brand-new silver iPhone 6 16GB for my wife today. Unfortunately, right out of the box it started acting as if I was constantly pressing the home button, even though I wasn't. It was constantly waking itself up, bringing up that screen that you get when you double tap the home key, and closing apps she was looking at. All without touching the home key. I tried to book a Genius Bar appointment, but unfortunately they don't appear to be setting any new appointments up until Monday. So I just went down to the nearest Apple store and walked right up to the first blue shirt I saw. He told me that normally they won't do Genius Bar appointments on launch day, but that the Apple engineers were very eager to hear any instances of defective iPhones. He actually had to go get the manager of the store (head honcho) because they were under a directive that the manager had to personally be informed of any defective iPhones. After listening to me and observing the problem, the manger went to the back and brought out a genius to specifically deal with my issue. He also was able to observe the strange behavior, and they replaced my phone on the spot. All of this with the store completely full and a line of people stretched out and around the corner. While they appeared to be turning people away for general service requests, they seem to be taking defective units very seriously.
