Touch ID being Erratic

Wife and I got iPhone 5s units at the same time. She has had hit and miss success with touch ID. I am golden with mine, and also hers when I put a finger into her phone data. She is frustrated, and will delete fingerprints and resestablish on her phone. Her finger scan will work for a few times, and then it gets to be like it doesn't recognize her finger (left thumb or right thumb). Is anybody else having some issues like this?

iPhone 5s, iOS 7.0.2

Not a reply, rather another fault with fingerprint recognition. I set this up at the store and it worked perfectly there. Now, after five days I can get to the code using any finger on either hand and with the backing film on or off. I suppose it is better than being denied but hardly useful as a security measure. Anybody else with this problem or solution?

Since a picture is worth 1K words, this might help.

As long as I avoid the end of any given finger when

registering, it works without failure.


Testing today, I have 20 apps in the background, several

which have push enabled, several with large graphics

displayed, several which can access the speaker (waze,

trip talk, etc and I can not get Touch ID to fail.


If anyone has an app that crashes and can cause TID

to fail, please post the app name. Thanks.


HTH,

Joe

While I won't deny there may be some with defective H/W, or some buggy S/W involved, I had problems too, and the fix for me was simple. I'd suggest trying it before doing anything drastic, or wasting time chasing your tail. Only takes minutes to try. Go ahead, give your 5S the finger. Just do it the right way ;)

Joe,

This post and your most recent one with a picture have helped my iPhone to work much better. I still get failures after time, but I also now get successes. Will keep watching to see if things degrade again...

One more update on my personal progress. I can't even get any finger to fail anymore by doing the following: 1. Manage my errant app conditions and low memory issues. 2. Register each thumb twice. 3. Use the pad of the finger and not the top of the finger, as has been suggested. Running 18 hrs now and zero failures, even with dry or damp fingers. I am happily using the system. Thanks everyone for the great information sharing. My wife still struggles and has turned hers off again. We will try it again using the three ways I have indicated above. I hope others are getting this down until a software update reaches out to us.

So i have been having the same problems as described, sometimes it works great, but then it stops working after about an hour or so, sometimes less... I have tried everything that people have reccomended to get it fixed, but it hasnt payed off. I really hope its a software issue, and now im downloading the 7.0.3 that just came out and hopefully it might make a difference.

Lets wait and see, ill post an update. 🙂

I have been running 7.0.3 since yesterday afternoon. I have conducted an experiment. I deleted all my prints, re-downloaded the USA Today mobile app (which had crashes when iOS 7 first came out), turned on the automatic app background refresh configuration, and then registered my three fingers again, just as single prints, not a second print on each thumb. Then let it work. My findings are at 99-100 percent success. I am not sure anything was done with TouchID in this software update, as there is no real mention about this in the fix list. However, it seems to be behaving much better. I am trying to get my wife to re-register her prints on her phone. This will be the big test for us. I should have a report today. Promising???

Oct 23, 2013 5:11 AM in response to Dreanmachine1

Just a potential key here with a software fix. It appears that one of the upgrades to iOS 7.0.3 is to delay the swipe to unlock function in support of the Touch ID being able to work first in the unlock queue. This fix could very well be a contributor to the software fix we were subtly looking for. Maybe this was the conflict that was grabbing us before in some measurebbI can't get my unit to fail anymore. It is flawless under very normal circumstances. Again, I will report on my wife soon as she has been the harder case to solve. I am hopeful.

Oct 23, 2013 5:29 AM in response to Dreanmachine1

Sorry, one other thing. When I push on the home button to wake it up, I now just leave my finger pressed on it with a gentle pressure and it goes in faster than it ever has on all three fingers. I hope folks that have struggled with this issue will report in with their results soon. I have a warm gut feeling that removing the potential conflict with the swipe to unlock message being available and the Touch ID option has nailed it.

Oct 23, 2013 9:36 AM in response to Dreanmachine1

I've had no issues for a while now after registering prints as Joe suggested and watching for memory/crash issues, even under 7.0.2. Still working perfectly after the update to 7.0.3. Hopefully this update cuts down on the frequency of crashes, etc. overall.


Incidentally, a little off topic, but iOS 7.0.3 made a change to the motion/animations when you toggle "Reduce Motion" under Accessibility. Previously, turning on "Reduce Motion" would reduce only the parallax effect, but now it also does away with all animations, like when unlocking the phone and switching or opening/closing apps. If you can live without those animations,Touch ID will unlock the phone much faster now with "Reduce Motion" turned on. The home screen will just appear, without having to wait for the home screen icons to "fly in."
