5s Fingerprint unlock problem solved
Like several (many?) here, I've had 5s fingerprint unlock issues since launch. Works
for 1 or 2 days only, requiring a re-scan.
I've finally solved the issue I've been having. Very simple fix...
I had been using the end of my finger only, with the very end slightly
over the far end of the sensor, varying the rotation between training scans.
This worked well for unlocking, but sadly failed over time.
My fix, which hopefully works for others: Use a thicker part of the finger.
It didn't take much, just stay away from the end of the finger. I also
moved more during training than the "move slightly" prompt you get
if you don't move enough.
So far I'm on day 4 and have not had any failures where I had
to resort to using the passcode.
If you have unlock problems, and this works for you, please
let others know to help spread the word.
HTH,
