Hello everyone!
I have bought an LG V10 (International Version) and I am having some problems with fingerprint scanner lately
Once in two weeks or so, when I unlock the phone with the fingerprint scanner, it reboots. I didn't know why this started happening. I don't have a case, so it is not related with that.
I found out that if I delete one of my fingerprints and I add it back, it stops rebooting. So that is what I have done for more than the last month I guess. Whenever it started, I just deleted my second fingerprint and added it back.
Now the problem is different. It rebooted once more. I deleted my second fingerprint and after that, I tried adding it back. I put my finger repeatedly on the fingerprint scanner and it gets stuck once, in 60%, once in 80%. It gets stuck and my finger doesn't register. You can see it in this picture I uploaded to pasteboard.co.
I am very worried because here where I live, we don't have a specialized LG store and if I take it back where I bought it, they will say that I broke it or they could try to fix and make things worse.
Has anybody else had this problem? Can you please help me out?
I remember this problem starting after my last update. You can see here my software information.
Thank you very much!

LG-P760 stock Android 4.1.2
Only basic apps, FB, gmail etc.
1. Factory/hard reset
2. Works around 3-4 days perfectly, then starts to crash.
By crash I mean black screen, nothing helps, only battery pull.
3. After first crash, starts crashing more frequently. Happens only in standby.
Worst was today: If I start phone, log in, then it wont crash before I put it in standby. First time in standby, within 30 second, it had crashed.
twice crashed when someone tried to call me. Vibrated once, then crashed.
I would like to avoid replacing my phone.
Any ideas how to find the source of this problem? Any recommendations?

I had the same problem with Vietnam Rom and it was the baseband. I changed to the baseband from ICS from a Rom of my country so I have Vietnam Rom+Original ICS baseband and everything works well.
Thanks.
Although, I understand it mostly is problem when you have unlocked bootloader.
I am running stock everything.
And they have problem with rebooting phone, mine crashes and freezes.
Weird is that it starts around third day of normal use.
I think I have to take on a quest with a warranty. Does anyone know, can I contact LG straight without the provider, where I bought the phone?

I haven't unlocked it. The problem was the same: SOD sleep of death, when the screen goes off you can't do anything but pull the battery.
But if you can use the warranty use it. You should find the warranty info in the box to know where send it in your city.

Thanks. I will search into it. Sleep of death is new expression for me.
I only have phone, it came from relatives who threw away receipt + box.
Luckily I managed to get new receipt from provider yesterday (I dont think they usually give out receipts twice), so now I can use local warranty.
Thanks everyone for replying. I will post update when I have final solution.
Since you are stock you might want to consider flashing the kdz to see if that helps. Good luck!

I'm having the exact same issue with mine. I've heard everything from "try a different SD card" to "factory reset," and nothing seems to permanently fix the issue. What I've found kind of sort of works is just reboot it a whole bunch until it finally comes up and doesn't do it any more. From there, I'm good to go until the battery runs out or I need to reboot it because all the bloatware is causing it to glitch. This usually means that I have to reboot my device 10+ times in a row every few days. Hopefully, you found a more viable fix than this.

Hi
I managed to kind of solve this issue. Because I am not sure how, I haven't closed thread yet.
Anyway, I warranted device, they re-installed soft. Came back, same thing. After around weeks use, SOD. Factory reset. After that, things went interesting.
I tried not to leave it idle. Always had something running. I also had noticed by the time it never occurred when it was plugged in or music was playing.
One day it did it again, but I was in a hurry and just disregarded it. I did something(I was busy, maybe just plugged it in automatically?) and it came back up. It took like 10 sec for screen to start, but it did just wake up. And it haven't had crash ever since. I have no idea is this solution or is this just some coincidence and I am not keen to factory reset again, to see will it reoccur. It's my only phone
TLDR: Managed to get out of sleep of death, haven't reoccurred since.
Hi all, I have recently bought an international Galaxy S6 EDGE. My fingerprint scanner was working fine until yesterday. My friend somehow managed to get INTO my phone with fingerprint locked. He was able to unlock it. I was shocked. He got into it twice. Sometimes it allows him to get inside, sometimes it doesn't. Today, I managed to unlock my phone, using fingers I have never registered before. I wiped my home button several times with wet tissue etc. Still same.
Light taps on the home button unlocks my phone. But if I hold my unregistered fingers there, it will show no match.
I am seriously confused. I hope somebody can shed some light on this issue!
Thank you.

Weird indeed, this never happens to me, though directly after turning on my device, i received an update, that said something about Fingerprint sensor, I don't know whether it was an issue that got fixed by the update. Maybe you should search for that update if you don't have it installed already

Latest updates already installed. No idea what is happening.. I already tried switching locks then back to fingerprint. Same thing.

Did you try deleting all fingerprints and assigning new ones? If that doesn't help I think your last resort would be a factory reset
Spoke to Samsung today. They say it's a known issue and the device needs to be reflashed or if it's less than 28 days old your entitled to a new phone.
So, for the second time this month my phone suddenly won't let me unlock it with fingerprint or backup password. I unlocked it with the find my mobile site. Bit now it is unusable. I have tried to registered my fingerprints again but with no help. Anyone have a solutions for this that don't need me to reset my phone? The sensor works in other apps like like finger security or paypal so it must be a software issue.
In advance thanks!
Do you have Greenify installed?
I have the same problem with fingerprint unlock no longer working.
It worked flawlessly for a few weeks then had occasional failures but now has totally packed up.
I have rescanned my finger several times and it will work for a day or two before failing to work at all again.
Is it me or is it a fault with the phone.
I do some DIY around the house, so it is feasible that my prints are eroded and causing it not to be recognised.
Is this possible? If yes, then a fingerprint unlock system is badly flawed and unreliable.

I am having the exact same problem..was working fine for the first few weeks, works 3/10 times on the first attempt now
I have flashed UK unbranded firmware and so far, it is working within the first 3 attempts.
My Alpha was working normally for 3 weeks, and then a day, it started to give an error when trying to unlock with fingerprint: "an error has occurred with the fingerprint sensor"
I unlocked it with password, then switched off fingerprint lockscreen. Then when I tried to turn it back on (click on the fingerprint manager) it dropped this error again "an error has occurred with the fingerprint sensor".
I have done factory reset, reinstalled with odin, downgraded to 4.4.4, no success. Then I took it to the service centre, they have replaced the home button and updated the software (to the same it was on it previously: 5.0.2 COI3, XEH region). The fingerprint worked at the service centre when I tried it. Then I went back home, done factory reset, few hours elapsed, then I tried to register my fingerprint, and this error showed up again. I reinstalled it with odin, with kies, downgraded to 4.4.4, deleted fingerprint app data, no success. I have found nothing helpful on the internet with hours of searching. It should be software related I think, it's very unlikely, that the hardware error (like unglued home button or something) occurred again, within this kinda short time.
Please help me, what to do. I would be very grateful
Im also having this problem, and many more people i believe. There are some fixes to this like heating it up or something. For some people it works, for some it doesn't.
EDIT: there's a video on youtube about it, you can try it.

I've seen it but I'm afraid that the screen or something will unglue due to the heat...
I ordered Premium Warranty Shipping, with spare phone, I hope they fix it but I will tell them firmly to replace the full phone or refund me the 510$ what's on the receipt.
But I'm open for any solution if anybody have it.

Your way of handling the phone is garbage. You are for sure an iPhone fan.
Sensor works 100%.

Going to second this, the fingerprint scanner works great for me, also slating a phone because it doesn't have any unofficial support is stupid.
Anyway probably best to send it back

i had this issue hair dryer really fix this issue ... if you are afraid of your screen ..put something on a screen like a book or anyother everything will be fine but .. it just a temporary fix u will get the issue again after 3 to 4 days again heat it up then problem will disapper and it will go on and on ....
So I have this Verizon unlocked SM-G965U and decided to flash it with firmware SM-G965U1, after setting up the fingerprint lock, it will shut off a few seconds after the screen goes off. If I remove the option to unlock the phone with the fingerprint it will not shut off. It started happening after I flashed it, and it did not happen before today.
I already tried flashing a second firmware, right now it’s currently on build PPR1.180610.011.G965U1UE6CSI1
I decided to update and change the firmware to SM-G965U1 because the one I got from Verizon wasn’t giving me updates at all (it was stuck on security updates from April 2019). I’m not in the US so I decided to go for the unlocked firmware model to get updates.
I found people who have had this in the past but no one seems to give a definitive fix. I don’t think this is a hardware issue.
Has anyone found this issue before and fixed it?
Should I try flashing another firmware coming back to the original model (SM-G965U)? (Is there any risk if I flash the firmware with carrier?)
Thank you!
So pretty much two days later and I have come to the conclusion that the issue with the phone is hardware related. I've don research online and several report they had the same problem after getting it wet, while others never got it wet, so that's why I had hopes mine was not a hardware issue. Granted I DID get the phone wet but the symptom described on the first post started after the second day i got it wet and right after I flashed my unit.
Just for the record, I flashed the phone back and forth from SM-G965U to SM-G965U1 (that's when I got the shutting down issue when fingerprint lock is enabled), reverted it to SM-G965U (tried at least two different firmwares), and finally settled in SM-G965U1 (I mean, why not?). I did try firmware with security patch prior to September 1st 2019 (since a user suggested that's when he got the issue on his phone).
Firmwares used to test:
SM-G965U1_1_20190816080114_wltpjfnoy9_fac
SM-G965U_1_20190910091240_jebmc6r22k_fac
VZW-G965USQS6CSH3-20190822152617
Now I see why nobody dared to reply to my post... I think I covered all the bases here, otherwise please let me know.

Nah... I never had those gestures activated to begin with. Besides, I performed a hard reset and even flashed different firmwares with no luck. Only option now is to replace the fingerprint sensor.
You're not the only one with this problem. The solution is to turn off fingerprint unlocked.

I hate to bump a old thready but I just got the s9 new to replace my s7. Upon setting up the phone with my finger print I am experiencing the same exact problem... Has this not been solved? Also turning off finger print log in seems like it's not addressing the issue. I've never had this problem with my s7 and feel like this isn't going to be good if a new s9 is already experiencing this problem...
Thanks,
