Hi. I bought an iPhone 6 on launch weekend and overall I'm very pleased with it however I have terrible problems with touch id. I set the phone up a new when I got it and it's on the latest software 8.0.2 but the touch id is terrible.I've registered a few fingers and even tried deleting them and doing it again but it still is useless. I can successfully register fingers and unlock the phone maybe once or twice but then it's like the phone forgets them and I get the try again message until I end up having to enter my pin. Anyone any advice? I came from an iPhone 5 so this is my first time with touch id.
