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!!

This Link is in the IHOP sticky in the dev section though flashing pudding or titanium is reported 50/50 chance of messing your finger print even if you re-flashed/rebooted or asked it nicely you might wana try this out
Most likely an issue of not enough free RAM for the scanner to initiate the recognition task.
Reboot the phone and it ll be fine. Real saviour is the alternate security code, which is your kickstand in case the fingerprint scanner gets jammed again.
Its not the same issue of that when you use TiBu and it confuses the scanner. My scanner isn't recognizing my finger swipes period. I think the scanner might be dead :-/

Op,
I had the same issue. The fingerprint sensor wasn't detecting any of my swipes. This is what i used to fix the issue. Shouldn't make a difference but i tried this on custom rom/kernel.
Turn off the phone, pull out the battery for 2 mins. Put it in and power on. Go to settings / security / change screen lock / fingerprint
Set up your pin and restart the phone.
Once the phone is restarted, go and identify your fingerprint, it will register the fingers and work as usual.
When my fingerprint thing wasn't working I rebooted and it was fine.
Check that you don't have some task killer killing the fingerprint sensor task maybe?
They don't seem to understand its not responding at all. Mine even does ghost swipes. I haven't found any useful info for this problem either. I don't know what it is because I've flashed back to nandroids that it did work with but now doesn't. It may have changed software that is not touched by backups or its hardware... couldn't tell you which.

Mine wasn't working at all,too. I guess it was effected from all of these roming madness. I just did like i posted #7 and it started to work again. Do you remember if you ever tried to use the fingerprint scanner with wet hands or something else ?
No wet hands. But it did go from working one swipe to not working at all. Ill try the battery trick when I get home as well as reflashing 2.34 if none work I'll assume he scanner died.

Thank goodness for someone reviving an old thread. Just unlocked my bootloader (with ltdanno360 help) and scanner stopped working. Doing this worked. Thanks!
Sent from my MB860 using XDA App
Great!!
My sensor wasnt working also, great Tip
omg, this thread just saved my life. I've been with a not working fingerprint scanner for 1 month now. And a simple reboot fixed it.
Just a tip: I had no need for the pulling off battery thing. Just rebooted and worked like a charm.
Thank you very much!
So, I got my 6P last monday. The Nexus Imprint seems to be missing on the security screen and the scanner does not work as when I set it up. Now when I restore the factory image it doesn't even show up in the setup like I did the first time I set up the phone. I tried clearing cache like another did on reddit per google's instuctions, but and it worked for a bit, but now it won't recognize anything at all. I am in communication with Google support, but wondering if anyone has ran into this problem?
The same thing happend to me this morning. Google Store support is sending me a replacement.
Just happened to me and I didn't even have my nexus a day. Already ordered a RMA device smh.
It happened to me after not even 4 hours of use. Mind you I set it up with one finger then deleted it. It has had maybe 10 presses.
When I try to access nexus imprint settings, I get the "unfortunately, settings has stopped" message.
I have only been configuring my device to have the same settings as my nexus 5 and deleting random google apps such as books - non essential ones then the fingerprint wouldn't respond. I'm not going to RMA the device for the failure but will try to isolate the issue and ascertain if it is hardware or software.
Yea they are replacing mine..... In the mean time it started working. So weird....
Does this actually mean its broken, though? I got this message, unlocked it with a pattern and not it works again. It might just be a process that wasn't running for some reason.

samething happned to me too. I downloaded the stock factory image (latest) and flashed and vola! it worked
Just happened to me, first time I've had a new phone go bad on me. Not excited about rma"ing it.
Wow! I just got off of a chat with Google and they need 1-4 more business days to get with me. No RMA or any type of answer. I don't get that if they have had other call in with the same issue.

Did you try to flash a stock image and see if that solved the problem? Might be something to do while you wait.

I have the same problem, i.e. no prompt about Nexus Imprint during first setup and no mention of it anywhere in the settings. I just flashed the MDB08M stock image and it didn't help. This is so weird. I guess I'm doing an RMA...

That's very strange. If I had to take a guess the imprint settings may only appear if the finger print scanner is detected as connected. Perhaps on a few units the fingerprint sensor isn't connected properly.
I want to make sure as well you guys flashed complete stock including kernel and locked the bootloader without having a corruption screen appear?

Yeah, after locking the bootloader again that boot screen disappeared and everything looks normal. I returned it to the store without any problems.
FYI, I had the same problem were suddenly my 6P fingerprint sensor stopped working. It would give me "Fingerprint sensor hardware not connected" or some similar error on the lock screen when I pressed my finger against the sensor. After a reboot the Nexus Imprint section went away in my security settings.
I contacted Google via their device support chat system, they pretty quickly jumped to a factory reset as a solution. I followed through with it and it resolved the sensor issue (during initial phone setup it worked perfectly). I prodded the tech for more information to the root cause and didn't get anywhere besides it potentially being a 3rd party app conflict.
I'm on stock Android with Feb 1 security patch and Google Fi when this happened.

i was on blissrom then i dirty flashed the newer version then the fingerprint option was gone...tried to clean install still nothing...ive just got it back by returning to stock/unrooting with the nexus toolkit..im too scared to root and flash again encase it goes away again...its such an annoying thing to unlock the phone with the power button....the fingerprint scanner is perfectly placed for easy access....FML

I'm on Bliss too at the moment and also missing finger print.
As I also miss slim pie, I'm trying other roms too. So far all of them did have finger print working.
(Still missing Slim pie, trying Benzo rom next.)
I rooted again and flashed blissrom and it's working again now fingerprint.... I flashed the version I was on before the problem happened.... Not sure whether to update again... Maybe I will wait for the next newer version......anyway happy its working and not some hardware fault.
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:
> Fingerprint seems better than B02 update.

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.
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.
