Anyone else not getting 100% success with fingerprint?

It works about 90 to 95% of the time for me. A couple things I've noticed:

- As a previous post said, thumbs seem to work better for me than fingers
- The thumb I use most frequently never seems to fail. The less I use a finger/thumb, the more likely it is to have a problem. (Although even then it's not too common)

Exactly. I'm at probably 95-97% of the time, but every so often you just mis-hit or your fingers are dirty or whatever it is. Nobody gets 100%.

nobody gets 100%? that's false anyone can get a 100% scan buy placing their whole surface of the finger that got scanned. The only reason you're not getting 100% like I said before is because you're using finger tips at odd angles. I just learned to make sure not to use my finger tips because that's what caused me to get bad reads. Now I'm at 100%
 
About 94%.
4-6% user error (wrong finger, side of finger etc.)
1-2% iPhone error.


FYI. There's also a great feature of the iPhone scanner that doesn't always get mentioned in these discussions: If it fails to read my finger I can try again and it usually works!!!! Try it!

I received my gold 32 gig ATT phone on September 25. Fingerprint touch ID on this phone worked 25% of time with 75% failure

Made Genius Bar appointment on September 29, took it in and they had me reinstall the software. Worked for a little while and by the next day would not recognize my prints. Got sick and tired of it made another genius appointment and went last night October 3

Since I am within the 14 day return. They returned the phone and gave me a brand-new gold 32 gig ATT phone brand-new in the box, the full retail box, not the replacement box. And it is working 100% of the time using the same exact fingers that failed on the first phone that I received. In fact the Home button doesn't even feel the same as it did on my prior phone and the on off sleep wake button isn't as loose as my prior phone

I Did contact AppleCare on the phone and trouble shot the phone through them but they wanted to send me out one of their replacement phones and while I know that that it's too soon for that to be refurbished I wanted a phone in a full retail box with the serial numbers that match my box so that is why I went back to the store and was able to obtain what I wanted. The Manager was very nice and without hesitation replaced it and I was lucky that they even had a 32 gig gold ATT phone in stock at 5:30 PM in the evening

Needless to say I am very happy with my touch ID. I could not figure out why mine would not work when my friends who all ordered the iphone 5s have no issue in using touch ID. the only difference is they did not have the gold phone

It's interesting to note that the phone I received last night at the store it's full retail box was manufactured at a different plant then the one that I received on September 25

Sorry for the long post but it's not always a software issue or that you're doing the fingerprints wrong in my case the phone was defective

which factory did the good one come from?
 
So far not a single fail, only user error (used the wrong finger), but will update if things change.

When I look it up it says china. The good one serial number starts with a "c" where the other phone which didn't work serial number started with a "d"

I don't know if that has anything to do with it but new phone's fingerprint sensor works fine. In a week of owning the other phone I never got that phone to work consistently. All I ever got consistently on the other phone was the screen that said try again try again try again that's the only thing that ever worked on the other phone
 
What i have noticed is lets say you scan only the arch of the fingerprint then try to unlock with the tip or side of finger it doesn't work cause the scanner is so small. You have to record and use the actual part of the finger that was recorded.

So what I did was something like someone else posted here said. I used 3 of the fingerprints for my right thumb which i usually unlock with doing 3 different locations of the thumb so that no matter where i place my thumb it unlocks it. 100% unlock rate now :)

Anyone else not getting 100% success with fingerprint? I've tried rescanning the fingerprint multiple times, it's still not 100%. It works like 90% of the time but that's not really good enough. Really annoying to have to retry. And no, there's no dirt or water or anything on it. It just fails randomly.

Works every time for me man.

Then your hands must be perfect, and must never get wet etc etc.

I was getting the try again and enter code on C3xxxxxxx till I abandoned touchID. so probably not related factory.
 
Works 100% perfectly for me all the time. I've asked hundreds of other people too and they all tell me the same. It works perfectly. So if anyone is having problems they probably haven't set it up correctly. Go to a genius bar for help. Apple does free iPhone classes.
 
100% here. I can place my thumb at any angle, 0 - 360 degrees, and it has always worked.

Sliding works 100% of the time.

Only if you enter your passcode correctly everytime without a typo. My scanner percentage rate is well over 95%, probably 97% or 98%. That's better than my extended passcode success rate.
 
100% Success Rate

I have no problem what so ever with Touch ID.

The primary finger I use to unlock the phone is my right thumb and when I use it the phone unlocks in a split second. The second, third and fourth fingers I have set up, take a full second to unlock the phone. Certainly not the end of the world, but a noticeable difference.

I will add though, if you alter your finger positioning on the sensor from the way you did the original scan, meaning putting less of your finger or the edge on the sensor, the longer the unlock takes and can result in the rare miss-identification.

Otherwise, if you always put your finger in the exact same position on the sensor, you should, I have, had a 100% unlock rate with Touch ID.

:apple:
 
It dosent seem to work well with dry fingers. If I lick my thumb and then touch the sensor, it works immediately for me. I have rough dry hands from my job and dry fingers sometimes don't get a good read on the sensor. I have deleted and rescanned my thumb once so far. So..... If you have dry cracked looking fingers/thumbs, it may not work so well. Get them moist and the scan works a lot better.
 
Biggest thing I found is to use the iPhone for a few days, and then delete all prints and rescan, placing your thumb in exactly the same way you pick up the phone and unlock. You won't be able to do this out of the box, trust me. Once I did this, and scanned a couple prints for my natural unlock motion/posture/position, it's been damn close to 100% accuracy. It's impressive tech.
 
Its really useful while I'm jogging because the iPhone locks and I type my passcode incorrectly most of the time, just trying to change music or something. Now with the fingerprint sensor, I just wipe my thumb against my shirt, place it on the button and I'm in :)
