I've gotten my screen changed today and it seems that the fingerprint reader is acting a bit weird.
As stated in the title I was able to enroll my fingers with no issues but it won't recognize them while trying to unlock apps or the lockscreen.
I've tried a few things:
- I've removed the lock completely even the gestures and added it again with the fingers
- Erase cache and Dalvik
- Wipe System and re-install it
I'd rather not wipe all my phone for now, I hope that someone would have another solution given it might not even work.
The phone is a Realme X2 Pro running LineageOS 18.1
So what happens when you try to unlock with your finger? Do you get an error message or does nothing happen? Is the new screen OEM or generic?

Just a generic "Not recognised" until there's too many attempts.
It's not a OEM there isn't a way to get one for this phone now but the seller says that it supports fingerprint and reviews of the product confirm it.
I would assume it's the shop that changed it for me that made a mistake but they've been great for a few years at repairing my phones.
My best guess now is that the reader must be registering a blank finger as it seems that I can keep registering the exact same spot.
I did a full reset it didn't fix it.
I think it's just not gonna work...

Hi.
My 13 year old son has my old galaxy spica, I can't remember which ROM is on it, but it does have CM 2.5.1.0 recovery.
He's currently in a lot of trouble, and I'm hoping the contents of his phone (texts) might shed some extra light on the situation, but it's currently locked, and he's being unhelpful, I believe with a SIM card lock asking for a PIN rather than an unlock pattern.
I was hoping repeated wrong guesses would force PUK lock, then I'd contact the network for a key (phone is in my name, I pay the bill) but I just get a 30 second delay after 5 attempts.
So, the obvious question, how do I bypass the lock, is it even possible without wiping the data on the phone?
Alternatively, can I just access the data, as I do have recovery on the device?
Thanks
edit - taking the SIM out still has the phone showing the "Enter Password to Unlock" screen
I think there's no way around that...the only way I know how to take the screen lock off is to do a hard reset but then everything off the phone will be gone...I dont think you can get around the screen lock AND keep the contents in tact, but I could be wrong...
Thanks - his brother just gave me the code
I suppose the follow on question - any way to lock someone out of the settings menu?
edit - solved -app lock (app)
Okay so this happened a few days ago and has still not been fixed. The problem is that when I go to unlock my phone with the fingerprint scanner witch is what I've been using since I got the phone. Scan my finger and it just keeps saying no match I do know the backup password and it unlocks the phone. But I have tryed to scan my fingerprint again through the scanner option in settings. It want me to scan my finger for verification as this does not work iv tried. I then go to enter the backup password to access the setting to change my lockscreen code swipe exc. When I enter the backup password it tells my the the wrong password has been entered. Now this same password opens my phone unlocks it just fine. But will not let my scan my fingerprint again or change my lock screen. Any ideas on how to fix this woth out a backup and restore? It's rooted so it's not big deal but I'd rather not have to.
Did a bit of research myself as i had the same problem, always remember to deactivate fingerprint scanner before making a backup (This didn't sound like your issue but just something to keep in mind). I found this post from another forum which fixes your issue.
You will be able to input new fingerprints into your phone from the settings menu once you have completed this guide:
Hahaha it's not a fix so much as a workaround. It removes your registered fingerprints without having to factory reset.
Ready? In recovery, navigate to /data/validity/ and delete "template.db"
This won't remove the lock screen setting so upon reboot the lock screen will still think you're using fingerprint... But your backup password will work.
I actually had to do a reset the only thing I can think of that happened was I had the finger print scanner as the lock on my phone before I rooted the phone. I'm not sure exactly but I believe that it deleted the "details" I guess that's the best way to put it. You know the way it makes you scan your finger in multiple times in different ways. I always used the same way every time thinking about it now I always had problems with unlocking my phone with the scanner I just thought it he scanner was total crap. But yeah I guess when I rooted the phone it did something or maybe I just didn't do it right the first time.
But the problem has been solved and the phone works fine the scanner is a lot better than I thought.

Give this guide a try for the fingerprint scanner if you wish to use the scanner. Always had issues with it till i found this and it has helped out drastically.

My issue is......while using the phone it jumps frpm what am doing then prompt me with the option to enter my backup password
As the title implies, I can never get my phone to unlock via the fingerprint scanner. I have 2 fingerprints set up and everything in the settings is turned on and configured, but when I'm actually on the lock screen it tells me is unable to use fingerprints and to use my knock code.
Am I the only one having this issue?

Mine has worked great. One suggestion would be to setup another fingerprint but use one the same fingers you already did. For example, I use my left index finger to unlock so I added another fingerprint, but used that same finger and tried to completely use a different side of the finger while setting it up. This way the scanner has more of a surface area to read and unlock with.
I just tried that. I added 2 more fingerprints from the same fingers as you suggested. Unfortunately, it didn't work.
As soon as I press the power button to turn on the screen, the dialog pops up saying unable use fingerprints. Please try the knock code.

Try setting it up with a pattern lock instead of a knock code. That worked for someone else who had the same issue

Have you tried completely starting over with the fingerprints? The few times where it didnt read my print I got at least 3 or 4 attempts before it told me to use knock code, so thats weird.

I didn't think of that. I'll give it a try and report back if it works or not.

Yeah I deleted the fingerprints several times and did the steps you mentioned in your first reply above. I still couldn't get anything to work.

I'm actually using nova launcher myself. After following the steps listed from a previous poster, i have had no issues at all. it took a few times, but then it started working and I haven't had any issues since.

I just had to delete my fingerprints once and it worked. I did it with the pattern lock

Hey guys, i have a problem with my fingerprint scanner. I registered my fingers and everything worked. then today i removed the fingerprint and tried to save other fingers, but when i try to hit " add fiungerprint" i always get the message "set up failed". How can i fix that?

You must be on the P beta?
I had the same problem and had to factory reset.

Had the same issue on Android P DP3 for several days.
TL;DR: nothing helped, had to do factory reset.
Precise error was Fingerprint registration error, please try again after trying to add a new one.
I think it had something to do with that hard coded limit of five registered fingers not being property updated after removing one.
Tried everything. Deleted all remaining fingerprints, wiped device cache via recovery, cleared various app storage&cache (google play services etc.). Nothing helped.
Neat trick to find out if it is the hardware problem is to create a guest account and try to add fingerprint there.
In my case that worked so I was 100% sure that factory reset would help.
If you have the same error and adding finger for guest account works I would suggest not to delete remaining fingerprints and continue using as is while waiting for Android P release and hoping this would be fixed there.
Isn't there a procedure for deleting the fingerprint/passcode files in twrp in case you restore a backup that has security? Maybe that would be useful...

Yes I had same issues with my Oneplus 6 dp3
I had little issues with my fingerprints so I tried to remove all fingerprints in my phone and add new fingerprints and I couldn't, it says "fingerprint registration error, please try later" I wiped cache. But didn't help but when I tried it in guest account it helped. But I can't use fingerprints anymore on my main user. So I did factory reset anyway since its not a hardware problem.
The issue is when we delete our fingerprints it's not actually deleting the fingerprints from the phone. There's some issues deleting the fingerprints from the phone
I found this by using "fingerprint quick action" application in play store
There's a option "work with enrolled fingerprints only" when this option is on only your registered fingerprint will work (as per security settings in my phone no fingerprint is registered)
But when I turn on this " work with enrolled fingerprints only" the fingers I register before deleting still works and my pinky finger (never registered that fingerprint in my Oneplus 6) and when I use that finger my phone vibrates ( meaning the fingerprint is not enrolled and the quick action won't work)
So the issue is the phone can't delete the fingerprint once registered
Sorry for my bad English. Hope you understand
Just wait for the next update which is comming out really soon and don't delete the fingerprints anymore till you get your update
I too had this issue on my Oneplus 6 Android Pie stock ROM (not beta) .
I resolved this by going into safe mode and registering my fingerprint.
Hold power button
Hold power off and then select safe mode
Register your fingerprints as you normally would
Reboot as normal
Did not need to clear cache or anything else.
Further fingerprint registration will need to be done in the same manner as above.

Did you solve this issue? If so, how? (I'm having the same problem, I'm not being able to register a single fingerprint).
I purchased my 4a to hold me over while sending my 4xl to get fixed(faulty battery connector, along with other bugs). One of the issues my 4xl had was a terrible lock screen delay after putting in my password or using face unlock. I chalked it up to slow facial recognition interfering with the unlock.
HOWEVER, I know now that the problem was not the facial recognition, as my 4a has had the same problem since I pulled it out the box and updated it. After using my pin/fingerprint to unlock the phone, I'm often met with this half transparent lock screen (see screenshot) that last anywhere from 5 to 10 seconds. This persist randomly in safe mode, and even after factory resets with minimal apps installed.
Is there a current bug tracker on this that I can't find? Link it if there is. Is there a workaround you guys are using? I can't imagine both of my devices having the same problem and it not occuring to anyone else.
Two different device similar issue ?
Could be the software you are running ?
Is it 100% stock ? When the device came out of the box did it not unlock right away ?
No delays on my device, touch the finger print scanner the phone immediately unlocks.
No delays here. Confidently can extend that to the overwhelming majority of 4a users who would be raising a torrid fuss if sign-in delays were the norm. Given it happened to you on two different devices/models you only need to look to the mirror to find root cause.
I found the cause and can replicate it across devices. It only happens when you're using pin + pixel print lock combo. Changing pin to pattern or password completely fixed my issues.
I cant believe I had this problem since the 4xl and it's my the pin option the whole time.

Strange, I use pin + pixel print lock combo (as I imagine is extremely common) and i don't have any issues. Maybe it's something deeper. At least you found a work around for now though.

"pin + pixel print lock combo" here as well; no delays. Try booting in safe mode to rule out personal app. All bets are off if rooted/unlocked.

Completely stock. Latest updates. As mentioned in my original post, it even happened after factory resets and in safe mode. I can grab a screen recording, as I still have this problem after performing a factory flash. I setup pin and print in the initial setup, and soon after I have the problem stated. Only way to resolve is to disable/change pin option.
I remember pin unlock being a problem in the past, but it was a while ago.

Hum - same weird problem on two different "stock" devices that isn't widely reported. Perhaps something related to your Google profile. Probably should reach out to them for further assistance or just stick with your workaround.
So I have this exact same problem with a Pixel 5. When I touch my fingerprint to the scanner, the screen stays black for 10+ seconds and then finally turns on. I tried the workaround (i.e. I switched from a PIN to a pattern), and so far I definitely see improvement. No issues so far. So I'll give it more time, but I think I may have replicated the problem and workaround. (on a Pixel 5)
Under Settings / Security / Device Admin Apps, do you all have an admin app configured? My employer has a special app for a VPN-like alternative and it has special admin privileges to validate the device security posture. I'm curious if it's related to having an admin app and security PIN enabled. It's probably an infrequently-used feature (relatively speaking), which makes it prone to weird unknown bugs.
