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

You're right, I did overlook this and it's probably the reason for all my failures. I expected too much, I guess. For me. the temporary change in the print seems to last probably half of my time. For example, I just washed my hands and it's taken about 25 minutes for it to get going normally. I wish they had put this in the opening lines of the page so I and others would have realized how little it can be used.


Paul,


If you're close to an Apple store, if I were you, I'd swap the phone out for a different one. If you've registered your print the way I've suggested, it does not matter if your hands were just washed, or you just showered.


The originator of this thread, Dreanmachine1, had the same issue as you; Damp hands after washing would not unlock the phone. He reported here on Nov 12 that he had the phone replaced, and it now works fine, just as mine does, with just washed hands. You can check his post back on page 22.


It should work fine seconds after drying your hands. Not that you would, just don't use soaking wet hands 🙂

Jumping in with a report 4-5 days after getting my replacement 5s that was from a different build week and a different China manufacturer (DN as the first two characters in the unit's serial number). Near perfect (about 98 percent success). With such a strong result for me, I got the wife's 5s replaced 1.5 days ago. Turned out to be the exact same manufacturing plant (DN) and build week. I was excited to have this to measure against. However, after 100 percent success, she had some strings of misses yesterday on both thumbs. However, my entry was immediately perfect with my thumb that I registered at the same time as her fingers. Her thumbs did eventually became responsive again.


What does this tell me? I think hardware variables are definitely in place with some manufacturing. There are also manifesting software/firmware constraints. There are unique finger and registration variables. Bottom line is I have come full circle that with a good manufacturing unit, and following the pristine registration strategies recommended in this forum, that the final piece of the puzzle is to isolate down into a version update that somehow resolves the negative boundaries with the software/firmware.


I think this forum can go on for 25K more reviews and numerous attempts to understand and drill down to one or two solutions. Much will help depending on what a person is dealing with. But until Apple gives us a software/firmware solution that removes the tight constraints or errant interface with other software system entities, we will live like this for the long term. I do have faith in an eventual resolution by Apple. Patience is gonna need to be practiced here. Keep bugging the Apple machine for attention in this matter. Thanks to all. This is what the forums are all about.

Your wife and I have the same experience, for me it stops working for a couple hours after a shower and for 15-25 minutes after washing my hands. So far, it eventually starts working again by itself. It's very consistent, and trying different registration methods doesn't seem to help. I have had this on 4 different phones. I assume replacing the phone would waste my time, so have no plans to do so now.


Did you let your wife try your phone, and, if so, did she have the same problems on yours as hers?

Hello dear friends.

Greetings fro Greece


I Also have problem with TID.i tried all your methods and none of them worked for me .After some hours or a day the most, any fingerprint stops working.Since i bought my phone ,it was working 99 % for weeks UNTIL i installed ios 7.0.2 update.till then you know.......

Did anyone else see changes after ios 7.0.2 ??

Nov 16, 2013 12:18 PM in response to Alxmaas

Agree. I had absolutely no problem with Touch ID until the update from a few days ago. I also changed my passcode recently. I would expect the update to be responsible for the problem. Every day, if I don't use my phone for an hour or so, when I want to unlock it, touchid doesn't work. It's not saying 'try again' or switching to the passcode view on its own, it's as if it's not even scanning for the print.

I am having (had) a related issue and have returned two iPhone 5s units to Verizon. Everything works fine for a day then not only does the touch sensor not recognize finger, the phone will not accept my passcode. As I use Exchange server for university e-mail need a "harder" passcode than the original 4 digit code when phone is set up. Neither the Exchange compliant passcode nor the original 4 digit code unlock the phone. There must be a hardware issue. The second phone had iOS 7.0.4 installed, the first one had iOS7.0.3. I hope Apple picks up on this as I will not get another iPhone anytime soon.

I have tried everything suggested in posts, and the touch ID only recognizes my prints for ~1-2 days, then I need to delete all and rescan. It's strange how it works very reliably for about a day, then not at all. Are my fingerprints changing that often? I don't get it...


The claim from Apple is that either you did a poor job of training initially or you had one of the asterisk items at the bottom of http://support.apple.com/kb/HT5883?viewlocale=en_US&locale=en_US (*Moisture, lotions, sweat, oils, cuts, or dry skin may affect fingerprint recognition. Certain activities can also temporarily affect fingerprint recognition, including exercising, showering, swimming, cooking, or other conditions or changes that affect your fingerprint) change your print. I talked to Apple Care yesterday and they advised to delete and re-create the print if your finger has changed permanently, or stop doing the offending activity and wait for your print to return to normal for the temporary changes.


My own idea is to try to create an additional print of after a shower to see if I can get it to work under all conditions. But, so far this hasn't worked.

Nov 18, 2013 9:31 AM in response to Dreanmachine1

I have had similar problems of frequent "try again" requests.


I have 90% solved the issue by scanning my finger again, but not deleting the first scan, so my unlock finger is stored twice. I may rescan it some more times in different conditions, damp, greasy etc and see if it gets up to 99% success.


anyway, summary, dont delete your scan, make an additional scan of your unlock finger. seems to help a lot

I'm trying this too, but the after-shower scan from yesterday stopped working after today's shower, so I had to use the password for a while today. Perhaps you will get better results than I. Frankly, if I had a store nearby, I'd probably take it in for replacement today, with all the time I'm wasting with it.

I'm just excited that it still is working after almost a day and a half; I didnt get results like that up until now.


🙂 🙂 🙂

With 3 more days I'm not happy to report that only 1 out of 3 fingers works, and the remaining finger requires even greater precision with placement for it to properly register. In order for the phone to open I must place my finger precisely. A little off in any direction and it does not register.


The control panel technique does not work at this time.


Also, I dont know if it's coincidence or not, but just like before my right thumb continues to work. Joe_Fo, how are you making out? Still satisfactory success?
