Fingerprint Sensor Trouble? Try This...

I mentioned this a while back deep in another thread, and thought it might bear repeating. Here's how I solved my problem with the fingerprint sensor:

When I had trouble with the fp sensor (maybe because I get dry hands in the winter), instead of overwriting my old thumbprint, I added my thumbprint as though it were another finger. Each time it stopped working, I would "add another finger" to the list (all of them my right thumb). I have 3 or 4 prints of the same thumb now, and the sensor is near 100% for me.

I saw in another thread that when you're looking at your list of fingerprints in the touch id settings and press a finger to the sensor, if there's a match in the list it'll be highlighted momentarily. When I do this with my multiple thumbprints, any one of them might light up depending on how I make contact, but one of them always does.

Sorry if this has been mentioned before -- I solved my problem early on, so I haven't read through all the fp sensor threads.

This is a really good tip, and something I hadn't thought of. Just registered both thumbs with 2 fingers each, working much better.

Another person said putting the same finger multiple times made their iPhone keep telling them to Try Again over and over, so I'm not sure this is a good idea.

i think I'm up to 3 different fingers for my thumb now. it works every time now.
Glad to hear it helped!

I have one scan per finger. Works fine as is.
I would expect it works fine as is for most people, or it would be one of those "-gate-named" scandals. This info is for those having trouble -- I tried to capture that in the thread title.

Maybe they didn't know how to delete a stored fingerprint??? Otherwise, I don't know why you'd have to be sure it's a good idea before trying it. If you try it, and it doesn't work, it's not a good idea, and you easily go back to how you had it before.
