So it seems that the 4a 5G has the same issue with Android 12, as the Pixel 6, and 6 Pro does, in that if you let the battery die, the scanner will no longer work, it works in that you can swipe down, and up and it opens the notifications, but will not even vibrate or anything when trying to unlock. Has anyone else had this?
I think I had this issue on my son's pixel 4a. His fingerprint stopped working, I suspect he let the battery die. I kept trying to set it back up and it wouldn't take. I ended up having to reset the security pin, remove all fingerprints and then set the fingerprints back up. At least I didn't have to factory reset.

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

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.
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.
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.
Just got the Pixel 5 a few days ago, and every 2 damn minutes it wants my PIN. What's the point in having biometrics if I can't even use the damn fingerprint sensor??
Is there a way to turn off the PIN requirement, or at least slow it down a bit?
This is not normal behaviour. Maybe your phone is having constant soft resets. Factory reset perhaps...
