Hi. I got an iPhone 6. I have a few questions. What's the difference between the standard or zoom view in the display settings and reachability? With reachability, once you double tap the touch id censer to turn it on, will it stay on until you double tap the censer again or will it sometimes turn itself off. I have also noticed a noise when I turn it off or on, but can't tell if the off and on sounds are the same or different. Anyone know? Also, what is Home Kit? Has anyone noticed that the touch id only works sometimes? I followed the instructions to set it up, but most times when I go to unlock my phone, it fails to recognize my finger 5 times, then forces me to enter my password. I am using the same finger to unlock the phone as I did to set up touch id in the first place. Restarting the phone and deleting and redoing the finger print did not help.
