I have a new i-phone 6S and my touch id is does not consistently work. I have entered various fingerprints and each time the latest print works for a short time and then quits; a previous print quits completely. None of my prints will work. I contacted apple support and a senior rep guided me to connect my phone to my computer to erase the software and reload it. After that, it began to work consistently for about a week. And now again the issue arises. I entered a new print and it will sometimes read that print. Now it will not read any of them. Has anyone else run into this issue? Everyone I know who uses an i-phone has not had my issue. I think it must now be a faulty phone (hardware) and not the software. Help! Any ideas?
