Touch ID being Erratic

version 7.1.2

still shows problem to read my finger. It's like 10 failures in 20 attempts to unlock.

I End up unlocking my phone with a pass code which makes me feel annoying.

they should replace my phone.

No improvement here on ios 8. Still works 100% for the first thirty or so uses, then goes downhill rapidly and I have to delete it and start a new one to get 100% again.

Mine's still wrecked. I gave up on it, figured I'd wait till iOS8...nope. Works for a few hours/scans, then rapidly deteriorates till it 100% doesn't work. I've even scanned in the same finger into all 5 positions...no luck. I'm on the phone to Apple again now.,

Not a happy camper

And Apple replaced the phone YET AGAIN, and >>>>>>>>>>>MIRACLE!!!<<<<<<<<<<<<<< it works FLAWLESSLY. They must have had a LOT of faulty sensors early on, because this is my 3rd handset. It works 99% of the time, except if my hands are wet, or I really put my thumb in the wrong place. It's been working steadily now for FOUR days, which NONE of the others did. If you are still having this issue, and are still under warranty (if you didn't buy Apple's extended warranty, shame on you!), ask them for another phone - INSIST on one. I bought my 1st faulty 5s in December 2013, got a faulty replacement in Feb 2014, but this one, manufactured six weeks ago, works flawlessly. Now I just got to train myself to use it all the time. It's FABULOUS.

A Happy Camper FINALLY!

So glad to hear. Hope it continues to perform as it should. I had no problems on my 5S for some time, which I think was my third handset as well.

Incidentally, I moved on to a 6 Plus last week and the Touch ID is great as well. It unlocks just a bit faster than the 5S.

My iPhone always tell me please try again when I am using touch ID to unlock my iPhone! I am so angry with this and I have to try more than 4 times to unlock my phone at some times I have to type in the password. What a shame!

Just wanted to say that I was having these issues on my iPhone 6, where I would only get Touch ID to work about half the time, at best. I would reset the fingerprints and it would slowly lose accuracy as many have said. For me, the Genius Bar replaced the screen on the phone (free of charge, of course), and I'm happy to report that I have had zero issues since. So far it's been about 10 days since then so I think it's fixed for me! Based on this, hardware seems to certainly be the culprit rather than software. The button also feels different... it's softer when you push and less 'clicky'... so if anyone's is clicky and having these issues, get it serviced! 🙂

It's been a while since I bothered posting about this.....

After 2 5s I gave up on researching this problem with literally trying all "solutions"

Found on the net., now with my 6 I was sooo happy it not only worked flawless for about a month but faster and

Brilliant but sadly after ages of pleasure using it it took back my joy with a vengeance.. It made me used to the awesomeness and

One day started to f*** up again.. Now it's back to my good old 4 out of 10 times :(((( I have to "clean" the button 80% of the time while

Work properly like Siri and maps :(((

Acually, you can clean up the Touch ID by your finger and try to place your finger on it again if your touch id failed.

I tried this: https://joshbetz.com/2014/12/better-touch-id-performance and it worked well on my iphone 6. Touch id became much more responsive.

I began experiencing this issue a couple weeks after buying my iPhone 5s and was totally puzzled about it. I almost read the whole discussion, and tried several of the suggested methods. In the end, what worked for me was changing the way I use Touch ID.

I'm not sure why the way I used it in the begining tends to work for a couple hours and then it stops to, but now it's working flawlessly for me. For what I read on the discussion, almost all of us have experienced the same problem, and my solution was quite simple: instead of using the top of my finger, I started using the center (where the fingerprint actually is). I sounds obvious, but the thing is that you have to put your finger in a different position than in previous iOs devices.

Maybe this discussion has become so long and complex because there are several different causes involved: in the begining it might have been software (for what I read, there was a glitch, but was corrected long ago), for some may be hardware, but for some others (like me) it may be just learning how to use it correctly.

I hope my experience help others overcome this annoying issue.

(sorry about any mistake I might have commited, but was you can obviously tell, I'm not a native english speaker)

Anyone who own 5S and TID have some a problem to scan , try put a scoth tape on it.
I just read the old post today and It worked like a charm !!

Right now I don't see " Try again" for 8 Hrs of used.

cheers!

Posted on another thread. Also noticed my Touch ID was working sporadically, but only when off Apple wifi (Airport), in particular while using xfinity. Switched back to Airport and everything was fine. Hmmm-

Is anyone having problem with Touch ID with iOS 8.4 on iPhone 6?

I am getting lots of ''Try again'' messages lately when I try to unlock my phone.

Then I delete my fingers and add them again and it's working for some time.

Also when I quickly wipe the home button with a cloth it works for a while then it

fails to recognize my fingers.

Deleting and rescanning prints will not solve the problem, not forever at least. In my case it was like that... I've had this with my 6+ and the only thing that permanently solved was restoring to factory settings first, then recovering from the latest backup. Backup on iTunes, not iCloud. So make sure to do a fresh backup stored on the computer, because it won't let you choose the iCloud one when you recover. Never had a Touch ID problem ever again, use several scans and they all always work. I mean unless it's me being inaccurate, having dirty fingers and such!
