Hello,
I have to set up finger prints again and again? I also use the maintenance tool regularly. Are some files, some cache, erased by the maintenance tool? Could it explain the fact that finger prints do not work properly from time to time?

Only had my phone a couple of days and it's already irking me in various ways. Set up 4 fingerprints and had to re-input them again today. Just disappeared.
Possibly related, face unlock was fully unlocking rather than going to lock screen. Hmmm.

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.

This finally worked. It took a couple of times to get it to finally be able to use the fingerprints, but it worked.
Thank you.

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

I am using Honor 6x. Is there a way to disable any sort of lock from lock screen but still be able to use fingerprint to lock certain apps?
Also is it possible to add multiple fingerprints and be able to unlock the "safe" in file manager only when i use 2-3 fingers in a sequence. What i mean to say is suppose i registered index finger of left and right hand. So i want the safe to unlock only when i place right index first and then the left index. Not with any 1 finger.I don't know coding so it would be better if anyone can make an app or a MOD to be flashed.

You should be able to disable lock screen and still use the fingerprint to unlock protected apps from device manager app, once locked... For your second question, setting a fingerprint sequence for unlock isn't possible (actually).
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'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...
