my fingerprint sensor is barely working, 4/5 times it fails to recognize my finger print. I factory reset my phone twice already. Does anyone else have this problem or knows how to fix it?
On my sister's Samsung, she gave up. Just uses a number code. The fingerprint sensor was too glitchy and then she had to use the number code as "back-up" verification anyway to get into her phone. So, saved time to just make it the primary and forget the non-reliable fingerprint sensor.
Sounds like you got a lemon. My wife's fingerprint sensor works very well, 90%+ success rate on the first tap.
No issue here, if I put my finger correctly (sometimes I hit the sensor with only 50 or 75% of the width of my finger) it works every time.
Some are reporting improvement with latest B03 update here:

Something to try: Cut your finger up into two halves (not literally!), register one half as one fingerprint, register the other half as another fingerprint.
Thanks for your input, maybe I did get a lemon. The weird thing is it was working fine like 2 days ago when I got it. It could be software related. Maybe I'll wait till the next update. I am on B20 is this the latest update?

B20 is the latest for the US model, but a new update is due out next week.
Try registering the same finger at least twice, maybe even three times...yes the same finger each time. And move it all around as you register it each time. Mine works every time...unless I hit it wrong.

I tried that and my sensor still fails to read my finger, I erased and registered my finger countless times but no luck.
How do you guys register mutliple times with the same finger? As soon as it detects another fingerprint with same finger, it resets the counter to 0. I can't get past 25%
Actually, what I noticed was, if you try registering the same finger, even though it's complaining that it's already registered, it's still adding these new scans to the original fingerprint! I'm pretty sure of it because after another 30-50 touches, it doesn't give me any more duplicate messages and stays at 0%.. if that's true.. that's pretty awesome. I've done every possible angle now and it doesn't show dupes.
Fwiw, I get about a 95% success rate and it only really fails if it's a *very* partial fingerprint. By comparison, I briefly had the Vernee Thor and there I got about 10% recognition rate under normal circumstances and maybe 50% under ideal circumstances (as in very careful positioning directly after I had set up the finger).
And, yeah, in my experience you can't add the same finger multiple times.

Anyone else having this problem,
Sometimes when I get to unlock screen and swipe across it doesnt react to it the first time and I have to do it again.
Yes. Many, many times. I resolved this by downloading an app that gets rid of the bar from me, so now I press home. Unfortunately this means I have no security on my phone. Yay!
Yea; I mean how much of a problem is it though? I guess it takes a second sometomes to initialize the scanner.

I am not talking about the finger printer reader, also at work I have about 1 second to check phone, so it just gets annoying when I spend that one second trying to get passed the lock screen
Oh! Yea that happens to me sometimes as well; I hate it.
It also "confuses" me when I slide it but there's nothing really being slid you know? Just the color.

Never had a problem with slide to unlock.
The finger scanner though, you have to remember at what angle and what direction you scanned in. Finding a comfortable swipe is better than trying to get a correct register. It's kind of like practicing golf swings.
I didn't have this issue till I did a factory reset, now the lock screen is soo slow.

Was going to say same thing. I did my 1.5.7 update a little bit ago and really having seconds from when I hit the power button until my screen wakes up. I can actually hit the button and scan my finger before it comes on. Anyone else having this type of slowdown?
Sorry for bringing up a old thread but kinda based on what I am dealing with.
My Atrix keeps waking itself up after putting it to sleep and STAYING on...
It is killing the battery life. This has only happened since the update...
Solutions?
I had that once before on my old build. Not sure what did it but it did end up stopping after a little bit myself. I think it was an app that was doing it

I would check to see if any apps are causing your phone to wake up; I remember this happening on my Captivate last year. I don't remember what the problem was but I knew it stopped after a week or so.
Something I have noticed with 1.5.7 the supposed fix to allow the phone to sleep while charging was a sinple change in the setting under development. I also have noticed when you place the phone on the charger if the lock screen is up and you are using the fingerprint scanner. you can never ( or should I say rarely) get it to stay asleep as it keeps reading the button press as a finger swipe. The only solution I have found is to make the the phone is on the home screen and press the button to make it sleep. then it stays asleep
I have had things like this happen to me, for a while I was using GingerBlur and I thought thats why the phone was glitching but when I went back to stock I had it glitch like this a few times on me also... I almost feel like my Atrix is running a beta...
I have not had any issues with the slider itself but i have observed this for a few days now. When i slide to unlock the screen, it goes directly to the contacts page and just freezes for a while. no other buttons work except hitting the home button and then ot works as usual. Any pointers? i recently rooted my phone and flashed it with the Alien rom [build #4 - 2.6.32.9]
Hello, I use a A2017G and have a problem with the finger print reader and DT2W features. When the phone is awake the finger print reader is pretty fast. Just tap and unlock the phone almost immediately. DT2W works fine then too.
But if the phone is in deep sleep (I suppose?) after around a minute the finger print reader takes almost 2 sec to unlock. It works only faster if I press the home button to wake the phone before tapping the fp sensor or if I tap twice (with a little break between). It's like I always miss the first touch and DT2W is slow as well (most of the time doesn't even recognize). I ve read on the zte forum about that problem but it couldn't be solved.
Anyone with the same problem? I think this is a very annoying issue knowing that the fp sensor is pretty fast.
I tried several firmwares including full reset... Nothing worked out. Some people said it could be a hardware issue but why does it work perfectly fine when the phone is awake?

Just found this post from a long time ago. My a2017g is only a few days old and I have the exact same issue. I'm on a fresh flash of B10.
Are others experiencing this as well? Only happens when the phone has been sleeping for a few minutes.
It is very annoying.
Try to hard reset

This is after a clean flash of b10 and a reset after that.
Are you not having that problem at all? Are you on a a2017g?
I'll try another reset tomorrow.

Well just to confirm, I have tried a full reset, and even went back to B08, and then applied the OTA to B10 (instead of flashing the whole B10 rom).
In all cases, the issue remains. The phone is very slow to unlock via the fingerprint scanner when it has been sleeping.
I do wonder if all phones suffer from this or if only some units do.
Any feedback would be appreciated.
I just got an LG G6, and instantly started having problems with the fingerprint sensor. It keeps getting "dirty" and will not scan my fingerprint 98% of the time.
I did not have that issue with my LG G5, so it is very confusing to me.

No problem with mine. It is actually the best fingerprint sensor I have ever used (s7, note7, iPhone 7). Sounds like a defective unit.
Mine is working perfectly, works 100% every time unless if I miss place my finger.
I've used mine with wet fingers. Dirty fingers from making pizza. Weird but yeah even with pizza dough on my hands it worked fine. I use mine upside down even with no issues
No issues here. I have 3 fingers/prints set up so far and all work flawlessly.
You should try re-entering your prints. When you enter them keep your head still and steady when pressing. I can barely touch mine and it registers every single time. What's awesome is I can use it to open my investment & work apps.

Mine works great. Try clearing your cache in recovery before calling it defective. Thats what i had to do with my jank S7 Active.

I tried this on my new V20 and the very initial results indicate it is right on the money. Thank you for this and I don't know why I didn't think of it myself. I suppose if it doesn't prove to hold, then I'm within my swap period, having the phone only 3 days now.
BTW - I initially scanned my fingerprint with the protective tape over the scanner, and despite re-scanning my prints into the security database, I wonder if that may have set up some initial cached data.

Fixed Fingerprint sensor LG G6 Not Workin
Disable Android's Device Administrator. Some how it asked me to set up a PIN, so after my finger was scanned I had to also enter the PIN
My fingerprint sensor used to work great, however it started prompting me that it couldn't read the fingerprint. I would restart the phone and most of the time that fixed it. Then, it got progressively worse. I would get three separate prompts that the "fingerprint sensor was not working" every time I would unlock my phone. Very annoying. Sometimes the setting for the fingerprint sensor would just straight up disappear. I decided to factory restore the phone, as I was having wifi and internet issues as well. Now, after multiple restarts, the sensor is not even recognized by the phone. No prompts and no fingerprint settings. Also the internet issue seems to have gotten worse. Really upset with this, as this phone is a replacement for my defective LG V10.
Edit: Just tested the fingerprint sensor hardware in Setting>General>Smart Cleaning>Test Hardware. It says "Not Responding. Contact a service center."
Fingerprint sensor works more of the time but suddenly it stops functioning!
Sometimes It does not recognise the fingerprint and, in the worst case, it totally stops to work like it does not exist or not connected; no life signal from it!!
In the first case I have to unlock with pin code otherwise I have to restart the device!
This is one of the reasons because I will never buy an LG!!
Happened twice since picking up my phone Saturday. The fingerprint sensor just stops working altogether. The phone makes no acknowledgment of tapping the sensor when on AOD or lock screen, and swiping the sensor to pull down the notifications does nothing. Reboot the phone and all is well again, so it doesn't seem to be a hardware issue.
Anyone else have this problem, any idea how to fix?
Phone is S8 on Verizon.
I think samsung just want to release update there are soo many bugs i also getting the same bug with fingerprint and iris scanner
Fingerprint sensor works fine on mine but iris scanner does not, times out during setup, i got it as far as 75% once
New phone, a lot of new software, will take time to iron everything out. On a positive note, I have not found any major issue that would actually bother me and some are my errors, I just don't know yet how to do it right. Sometimes clearing cache fixes problems like this, but since I don't have the issue, can't test it.
I guess I could try clearing cache the next time it happens. Happened twice yesterday about an hour apart.
There's a solution that I haven't tried yet in this thread:
https://forum.xda-developers.com/galaxy-s8/help/fingerprint-scanner-issue-solution-t3602551
The fingerprint sensor has been working for me just fine ever since I got my M3, but today it suddenly became unreliable. I have to try several times to get it to work and I have to move my finger around on the sensor before it will detect. I decided to delete and re-register one of my fingerprints. When I try to register now, the registration screen will register 4%, then it won't go any further. After a few tries, it says "Unable to register, please try another finger, etc."
My tab is a WTV-W09 on Android 7, EMUI 5 rooted with SuperSU. I haven't done any software upgrades, so I don't know what would cause the change. Does anybody know what the issue might be?
I've found that both my mediapad and my LG G6 are struggling to get a good fingerprint read in the past few weeks. It seems to be related to the cold dry weather. Even when I'm indoors, my fingertips are very rough, dry, and often chilled, compared to more normal weather.

That could be the problem. I'll experiment some more and see.
