Unresponsive fingerprint reader - T-Mobile Samsung Galaxy S8 Questions & Answers

Anyone having issues with fingerprint reader not recognizing finger right away.

I've experienced losing my fingerprint recognition. My fingerprint was working really well but after applying the latest red tint update, it seemed to become not as responsive. When this happens I find that booting into recovery mode and clearing system cache partition, then rebooting usually fixed it. If that doesn't fix it, i remove the old fingerprint and register my fingerprint again. Then it works excellent again. One quirk that i have is that it only seems to recognize only the 1st fingerprint easily but doesn't recognize a 2nd fingerprint as easily. Took me forever to tap my 2nd finger many times to get it registered and even after it did, that 2nd fingerprint wasn't recognized reliably by the sensor.

Has happened on 3 separate occasions for me where it just stops recognizing any finger at all and requires pattern input to unlock. A reboot always fixed it for me.

Fingerprint Scanner Issue

Has anyone noticed a issue with the fingerprint scanner just not working? I have had it twice. I have a friend on a S8+ with the same issue. It requires a restart to fix it.
Yeah, it happened to mine when I went to the gym. My phone was a little wet from sweat and it would not work. A quick reboot fixed it. A little annoying, something that will hopefully get squashed.
I had this issue for a few days, but I don't think I've had issues after I updated. Since I updated, when I thought it wasn't going to work, I'd either slightly change my finger position or hold my finger on the sensor longer, and it would unlock. It's just a crap location lol.
I had the same issue. I did some research and found that dialing *#0*#, clicking on sensor, then scrolling to the bottom under FingerPrint test and clicking normal scan seems to have helped. I haven't had the issue since and it's been a few days.
I had to turn the swipe down for notifications w/ fingerprint to get it to work again.
Happened yesterday, after I touched it with a wet finger. Restart fixed it.
I am having the same issue

Unresponsive fingerprint sensor

Hey guys,
Recently, I've been having issues with my fingerprint sensor/unlock screen. Sometimes when I pull my phone out of my pocket and attempt to unlock the phone witht he fingerprint sensor, it won't respond. I then press the power button, which turns the screen on and when I use the fingerprint sensor, i can feel the vibration from the button but the screen does not unlock. There is also no fingerprint icon at the bottom. I can't unlock by swiping and putting in my password either. This eventually fixes itself after 30-45 seconds, but its really annoying when I want to use my phone. I've tried switching launchers, thinking that this might have been the problem, but this did not fix it.
I'm running stock OxygenOS 4.1.6, kernel [email protected] #1. I'm using the google launcher currently.
Its something to do with the light sensor cause i have it happen at night time when i am listening to podcasts in bed, it comes up to press one of the volume buttons and back to bypass it - but after 10 seconds it lets you unlock it anyway?
Pocket mode, try turning that off. Pocket mode uses the proximity sensor (I think) to detect whether it's in a pocket or not. If it is, then the fingerprint scanner will refuse to work so as to prevent accidental touches in the pocket
Turned it off last night. It's still happening. And it happens even when the phone is sitting on my desk. I go to try and unlock it and it won't respond.3
Delete and reset them. I find it happens after a month or so of use. I'm on Sultans marshmallow.
Originally when it happened I thought the ROM had gone bonkers and flashed back to stock. I missed the battery life too much on the CM13 build so I tried his marshmallow again. And guess what? It happed again. So I just deleted them and reset my fingerprints and voila! Snappy again.
Let me know if it works for you!
Just delete your current fingerprints and reset them. Should become snappy once again.
Happened to one of my friends and that's how I fixed it for him.
Cheers.
Never had issues with. Maybe you use it wrong side of finger, i mean you must unlock with you finger horizontally and not vertically finger

My phone has started acting wonky, not only with the finger print sensor but sometimes the touchscreen will become unresponsive, but I'll be able to turn the screen on or off. I'll have to try resetting tonight.

Problem with fingerprint scanner

Lately the fingerprint scanner won't unlock the phone. There's no vibration indicating wrong fingerprint, it just does nothing. When I unlock the phone using PIN it works fine opening top notification panel or scrolling through photos. When I go to settings and fingerprints manager it recognizes my fingerprints without a problem. Even when I lock the phone it works well for couple of times but after a while it stops working again.
Have anyone had an issue like that?
I already switched the phone off and on again but it changed nothong.
Any advice besides resetting to factory settings?
Thanks for any help
Hey, I have the same problem with my Honor 7. Did you find any solution?

Are u using something like double tap to lock.
If so, disable it.
Otherwise, go to backup and reset, and reset only settings.

Fingerprint problem after changing screen

Hey everyone,
I just changed the screen (with the full assembly) on my P10 and I have a weird problem with the fingerprint sensor.
I can add new fingerprints just fine, and if I try to set the same finger 2 times I get a message saying I've already saved this fingerprint. But, I can't seem to unlock my screen with the scanner. The screen wakes up when I scan my finger but the phone doesn't unlock even if the option is activated in the options.
I really don't know what to do.
Same problem here, is software related problem. Try to do a factory RESET. In my p10 was solved on the pie update.

Fingerprint unlock any finger

I just factory reset my P10 on the newest pie version and noticed a concerning thing. When I enrolled just one finger print ex thumb then tried to unlock with any of my other fingers I world get a vibration of failure but if I kept on doing it quickly I could get access to my phone. I did get my wife to try the same method and she was unable to unlock phone. I tried the identify finger print in the setup menu and it identifies it correctly and will not see a non enrolled fingerprint as one that's enrolled. This is a somewhat concerning thing to me. Just wondering if others have had the same experience.
If it unlocks to you but not to your wife (same phone?), don't you maybe have your face registered for Face unlock - so it recognizes your face (not finger) and unlocks
Also, check Smart (un)Lock settings, it maybe unlocks based on trusted BT devices (or trusted places)
Good call. I guess tapping the finger sensor that many times wakes the device but not screen. I had to turn the screen almost sideways to make sure face unlock didn't see me tested then all worked correctly.
