Hidden Touch ID feature

[TheColtr]

Has anyone ever added multiple fingerprints to Touch ID but then forgot what fingerprint was which? I'm running iOS 8.3 beta 3 so I don't know if this is specific to the beta, but when your in the Touch ID settings if you put your finger on the home button that finger print in the Touch ID settings will get darker.



You can see when I put my right thumb on Touch ID my right thumb fingerprinting the Touch ID settings got darker. It works on my iPhone 6 running iOS 8.3 beta 3 too.

Cool, you learn something new everyday.

That's not really hidden feature, I've used it before with my 5S over a year ago.
Apple has it on their page: https://support.apple.com/en-us/HT201371:

If you have more than one fingerprint enrolled, you can touch a finger to the Home button to see the fingerprint it is linked to in the list. If your finger matches, that finger in the list will highlight briefly.

Cool tip! I didn't know that either.

Another cool feature is that if you activate Siri with a finger that's been enrolled in Touch ID, it won't prompt you for your password for reading your messages and other similar functions, unless it got a bad read of your fingerprint (which is rare).

You can also name your fingerprints, which makes it less likely that you'll forget.

Actually this is for when touch id becomes less accurate, if you put your finger in there, it reads the fingerprint again and touch id becomes more accurate.

As these posters stated, both these have been around for a while. Not new

Sounds like an urban myth.

I think it did this back in 7.0

If neither your fingerprints or their saved data changes, how would touch id become less accurate?

It isn't actually. Try it and you'll notice that if you register only the right side of your finger and then enter the Touch ID menu. You can slowly adjust your registered print to the left side and it will have forgotten the right side.

It's been like this since iOS 7 and iPhone 5S. Nothing to see here, move along....

Great question but it does.
Did on my 5S and now my 6+. I have to periodically refresh them - for some reason the "thumb" read seems to degrade quicker.

Siri can read my (new) messages without unlocking my phone.
