Anyone else having a problem with Touch ID? I got my iPhone 6 a few days after it was released and everything was working fine and one day my finger print stopped unlocking the device. So I headed over to settings and found iPhone unlock, Apple pay, and iTunes & App Store was turned off. When I tried to re-enable I got an error. If I tap the iPhone on a table it will start working for a while but eventually stops. Anyone else having this issue. I'm waiting for an exchange because the place where I got the phone has been out of stock.
