Fingerprint sensor "forgetting" fingerprints

post #1 of 37
Thread Starter 

I hope this is the right forum to put this question in.  

 

I have a 5s, purchased a week ago.  I have set up both of my thumbs and index fingers on the fingerprint sensor.  It works great at first but by the next day, it forgets my prints.  It *might* work sometimes - like 1 out of 10 attempts.  But not like at first right after I scan when it works every time.  And then eventually, won't work at all and I have no choice but to re-scan.  Then after I re-scan it works fantastic but by the next day, not so much.

 

Is anyone else experiencing this?  Am I doing something wrong, or is it supposed to do this, or is something wrong with my phone?  

 

Really frustrated...

Yes, it’s specifically designed to do that.

Wait, what? It is designed to forget your fingerprint scan? What does rescanning mean (I don't have the 5s yet)? Does that mean you have to re-train the system to recognize your fingerprint? Everyday? Wouldn't that be like the phone forgetting your passcode and you have to reset it every day? How is that convenient? I must be missing something. Do you have a link?

TS was joking. Obviously it is not designed to do that. It sounds like a faulty unit producing large variations in the scan data. Or maybe she's an alien?

No, it is.

 

An Apple spokesman pointed to other security features the company has added to the phone. Apple customers who wish the use Touch ID also have to create a passcode as a backup. Only that passcode (not a finger) can unlock the phone if the phone is rebooted or hasn’t been unlocked for 48 hours.

OK, but that doesn't sound like ranchogirl's problem. She's saying her phone forgets her fingerprints by the next day. So maybe it is a defective unit. But even still, why does the phone do that after 48 hours? Did they give an explanation? Do you have a link to the actual article?

Agreed - but it doesn't require you to re-enter all your fingerprints, so I don't think that's the issue here.

Same problem. I deleted and re-entered my prints, and the phone worked fine for a day. Now it has forgotten them again. Back to the Genius Bar, I guess.

I'm no expert but I'm thinking that it's not a hardware problem, or it wouldn't be working fantastic for that first day, but a software problem.  Like something in the software is forgetting the print prematurely.  And being that it might possibly be a software problem I'm surprised that more haven't spoken out that they are having the same issue. 

 

On Saturday I rescanned 5 fingers - right and left thumb, right and left index finger, and right middle finger.  All worked fine until Sunday (yesterday).  On Sunday both index fingers and my right middle finger worked fine, left thumb worked sometimes, and right thumb didn't work at all.  Rescanned right thumb - my most used finger to unlock the phone.  As of right now the right thumb still works great and I'm actually surprised.  But left thumb doesn't nor does left index finger now.  The biggest surprise however is that my right index finger and right middle finger still work with every attempt and I scanned those on Saturday.  

 

I don't think I'm updated to 7.0.2 yet, so going to do that now, and the next thing I will try is just having one finger scanned, until I'm really confident it's working.  Like 48 hours without a hitch.  Then add another finger.  If all else fails, my 14 days are up on the 7th, and I'll return to the Apple Store for an exchange.  I'm just worried that they won't have my phone in stock.  Ugh...

And here's the other thing - I can just imagine a Genius Bar appointment - hello sir, my fingerprint scanner isn't working.  All they'll do is show me how to set it up and then wala - it will work great!  Unless they are going to go home with me to verify when it stops working, it will be hard to prove a defect in this scenario.  

 

I'm hoping that as long as it's within the 14 days I can exchange it just because I want to.  However I feel that they will be more likely to have my phone in stock as long as there is something wrong with what I'm bringing in.  Just an inkling.

I don't see how it can be a software issue - everyone has the same software. The only explanation that seems plausible is inconsistent scan data that varies with time - a hardware problem. I would definitely request a replacement. Have you call Apple support?

No I have not yet, as I've been trying to determine if it's something I'm doing incorrectly, or if it's the phone, and if others are having this issue too.  

 

If I call Apple Support and they determine it should be exchanged, would they be able to reserve the same phone for me in the store?  I have a silver 32GB, which I understand is still hard to come by.

I read on another Apple forum that quite a few people are actually having this exact same problem.  One of them returned her phone for a new one and the same thing is happening.  Several posters have commented that it could be the user's fingers that have issues, not the phone.  

 

I also noticed that it's usually my thumbs that I keep having to re-register.  Right now my index fingers that I registered on Saturday still work. 

 

So, I'm conducting an experiment.  I registered my daughter's fingers in two fingerprint slots.  If, in two days, the phone forgets her fingerprints too, then it's probably the phone.  If it doesn't, then it's probably my own finger issue.  

 

I'll let you know the results of my experiment.

On the advice of the Apple tech I chatted on line with, I did complete software restore on my iPhone 5S. It is now remembering my fingerprints perfectly a few days after I inputted them.

How do you do a complete software restore?  Go into iTunes and select restore?  How is that different from syncing?

 

I was just coming on here to state that there is nothing wrong with my phone, but rather, with my thumb.  The phone still remembers my daughter's fingers, and one of my fingers (index).  But, not my thumbs.  Fwiw, my thumbs are not callused, but they do get dry.  Still doesn't explain why they work flawlessly on day 1 and maybe 2, however...

 

I will try the software restore.  

post #16 of 37
A software restore will completely erase your phone and then install a new copy of the phone software. Then it will restore all your apps , music, photos, etc. Be sure to back up your phone in iTunes before hitting the restore button. Good luck.

Yup.  There is absolutely nothing wrong with my phone.  My index finger still works perfectly, every time, fast, and it hasn't forgotten it.  Same with my daughter's fingers.  Works perfectly every time.  My thumbs on the other hand, it doesn't like.  Well it likes it on day 1, but not past that.

 

I called Apple.  They said that they were aware of the problem and that there will be a software update soon with a fix.  It seems that with fingers that it can't read as easily, the memory of the print that worked so well initially gets deleted.  Such as my thumbs.  The ones it can read easily, such as my index finger and my daughter's fingers, and most everyone else's fingers in the nation, it remembers.   

 

My thumbs are not calloused but they do get dry.  

 

So I'll be patient for now.

post #18 of 37
We have 2 phones, both forget the thumbs. When it works, I love it - just push and open. If I have to have to handle the phone to use index, then I may as well just swipe. It happens to people so often that you know it had to happen in testing. Odd
post #19 of 37

I have tried all kinds of fixes. I downloaded the new software update 7.03. Each fix only works for a short time then the phone forgets my fingerprints again. The only way to get the phone to open with prints is to go in and delete the old prints, record new ones and then the prints work for a few hours or up to a day. Then once again I have to go through the whole process again. I can tell the phone is no longer recognizing the prints because when I go into settings for fingerprints the print no longer gets the grey bar over it (which shows it recognizes the print). It is easy to check- record the print and the bar is grey over the print. Come back 4-5 hours later and the same print no longer gets the grey bar.

 

Not sure what can be done to fix this, but it is supposed to be a major new feature of the phone and it is a dud.

 

Will try to go to the apple store soon, but don't have much hope as it seems to be a software issue.

Maybe you're just holding it wrong?

post #21 of 37
It's happening to my phone also. I register my print and my phone forgets it within a day. I'm presuming that there will be a software update soon

Quit cleaning your sensor...you're wiping your prints off. :p

post #23 of 37
I have the same problem, my iPhone 5S soon forgets my fingerprints and stops recognizing my thumb. I only hold my phone with my right hand so only use my thumb. Sounds like the thumbprints are the ones easily forgotten, unfortunate for me. :-)

I'm glad I found this thread and won't try to exchange my phone.
post #24 of 37

+1 for this thread. I'm having the same exact problem. But surprisingly, I'm not seeing any other threads online about this "forgetting fingerprints" issue. This seems to be the only one, and not very many people are posting here, which makes me wonder if we're dealing with a general software issue or defective sensors on specific phones. Would like to hear what others have to say about this, or of other threads on this problem if they exist. 

post #25 of 37

Yes, it makes me wonder too. I also have the issue that it seems to work less and less over time. I'm also thinking it has something to do with the sensor itself or the software. I have an HP laptop with a fingerprint reader that I setup four years ago and it has never failed. If it is a software issue, then Apple will likely correct it in a future release as long as enough of us make noise. If it's hardware related, then I guess we'll have to wait for the iPhone 6 to get it corrected...

Nice false concern.

There have been people experiencing the same issue. Just go on Apple support pages. I haven't had any problem myself. But you have either a faulty unit, or maybe some configurations of print or skin types work less than others.

 

https://discussions.apple.com/message/23989897?ac_cid=tw123456#23989897

 

I don't think that 39 pages of forum indicates that it's a huge problem, but it might appear for a small percentage of people, which is, understandably, annoying. It should 'just work'. For me it was the case. Re-register your prints slowly without cleaning your fingers before in order to avoid removing moisture.

 

What you are describing is a pretty odd problem though. Try changing your unit.

post #28 of 37

The same thing has been happening to me!! I have had my iphone 5s for less than a month and I thought that I had a defective one.  I have been on the phone with technical support for more times than I would like to admit.  One of the support teams said that it was because I did not have deep enough ridge detail (which at first I kind of believed), but then I remember that like you, I would reset and it would be perfect all over again.  Then much to my surprise....it would stop reading it again!!!  I am beyond frustration!

post #29 of 37

I have exactly the same problem!!!  Apple when are we going to get a fix for this....Awesome when it works.

post #30 of 37

Same problem.  I had to try 3 different phones at the Apple store before I could get fingerprint to even be accepted.  Now, my fingerprints work for 24-48 hours perfectly and then it deteriorates to not working at all within another day.  It is a great feature but actually is worse than the old 4 digit passkey because it is so unreliable.  Apple- what is going on?

post #31 of 37

This doesn't explain why it forgets both my fingerprints I enter....It has to be a problem with the phone.  Why does it always work perfectly for 24-48 hours if there is some kind of problem with my specific fingerprint?

The software is working as intended.

Except if you’d read anything, you’d see it’s designed to do this.

I have read things but are you seriously saying  that $xxmillion 5S users are re-inputting their fingerprints every 24-48 hours and that is what the phone is designed to do?  I have spoken to Apple and they do not think my situation is at all normal and are putting it down to a repair job....

No it isn't. It should only forget the fingerprint if the phone isn't unlocked in 48 hours, or is rebooted. The phone shouldn't just spontaneously forget the print after 48 hours of regular use.

Exactly, and the way I understand it, even then it doesn't "forget" the fingerprint. It just requires the passcode to unlock it.
post #36 of 37
This may seem funny but try washing your hands, the finger scan is very sensitive and the excessive dirt from your fingers may be interfering with it recognizing u. It worked for me
post #37 of 37

My fingerprint sensor worked just fine.....until I downloaded the upgrade. I've tried to rescan, but it will only unlock with the passcode. Frustrating.
