I tried all pie roms(havoc, nitrogen, pixel experience )but the face unlock is not working properly at all . It works fine at first but after few minutes my phone only accept pin or fingerprint. Is it same for you?

After restarting my Mi5s the fingerprint scanner doesn't work anymore. The same issue appears when I put the phone off and I put it on a day later (I like to put the phone off while sleeping).
I know that the first time after restarting the fingerprint doesn't work by Android default. However, it also doesn't work thereafter. When I remove the fingerprints in settings and add new ones, it works again. Does anyone have the same issue and a possible solution?
Not having this issue. Which ROM version do you have installed?
I use the xiaomi.eu stable rom.
Ah ok, custom ROM then. Please ask in xiaomi.eu forum, they might know more.

I had same problem here after I encrypted my device with 'encrypt device using lock screen'. When I switched encryption off the problem was solved. So seems a software problem. I am working with most recent stable Global Rom (8.0.3.0). Hope it will be solved in next release. China stable was released a few days ago.
had that problem with miui.eu , it was an outdated version of supersu and twrp, updated them and problem solved.
I installed the Android p but I went back to the pixel experience on the G5 cedric bike and I can no longer use the fingerprint, someone can back up the partition / vendor or have some suggestion or had the same problem and solved it
The same thing happened to you. I do not know how to solve the problem.
I have same issue with moto g5s plus. I had installed android pie rom after that i lost my fingerprint scanner so i rollback to stock 7.1 but no fingerprint showing. so i thought i lost my fp scanner i have to give to repair my phone at night i got soak test update 8.1 so install it. At moring i checked my phone and my fingerprint scanner option was back. I though i was luckey. No one have posted any issue regarding this so i thought my be hardware was having issue. But after reading your phone i think you can also try this maybe it will fix your error. If it does i maybe right if not there my be other issue i have understant it wrong. If it work just post it worked. I will be happy to help you good day.
Hi I dont know what seems to be the problem. I flashed the rom and everything was working fine last night. Today after cooking i tried unlocking my phone but its not working. The fingerprint icon still shows.
Im on LOS 15.1-2018521 nightly
Hey so I'm new to the OnlePlus 5T. I used to be on the 3T and never had any issues like this, I was a flashaholic on that device so I know my way around the process of flashing custom roms. Or at least I thought so?
So before I ask, here's what I'm running:
- Latest OOS Firmware, I believe 9.0.4
- Resurrection Remix Pie (Official), Dumpling.
- TWRP (Can't remember the version but it's the latest by codeworkx, was posted this month)
- I AM encyrpted
- I AM rooted with the latest Magisk
So here's what I did: Yesterday I got irritated by the lack of official RR updates, so I tried out an unofficial luisroms build. I reverted back because I realised not much had changed, but when I restored my backup I couldn't get into my phone as it said I needed a password even though I made sure to remove all lockscreen security before making the backup in the first place.
After a few hours of trying, I got in but couldn't register a fingerprint. It just wasn't recognising my finger when I tried to actually set it and stayed on the "Touch the fingerprint sensor" screen.
So I went back to Oxygen OS, made sure I was fully updated and encrypted and then re-flashed official Resurrection Remix Pie for Dumpling.
(Important: As of this point, the fingerprint sensor was working perfectly again, so the physical sensor is working fine!)
I've only just got the phone fully set up, I removed the lockscreen security (Including the fingerprint) and went into TWRP. I made a backup. Then I rebooted back into the OS and now when I'm trying to apply my fingerprint again, it's not recognising my finger. Exactly the same as it was before I re-installed OOS.
So summary: TWRP Backups and Restores are breaking my phone's ability to use the fingerprint sensor. Is this a known issue, and how do I fix it?
Thanks for your time, hopefully the good people of XDA can help me out here :good:
EDIT: Progress has been made, ish.
By going into root/data/system/users/0 and deleting "fpdata" and "settings_fingerprint.xml" I can now get the fingerprint setup to recognise my finger in the settings, but right as I'm about to do the final fingerprint press to set it up I get the error: "enrollment was not completed. Fingerprint enrollment didn't work. Try again or use a different finger"
FURTHER EDIT: So as unrelated as it seems, with the issue happening right after making a backup in TWRP, it appears the issue was caused by a Magisk module called NFS-INJECTOR. Not knocking that project, it's amazing and I'm still using it, but after disabling it in magisk and rebooting I was able to set a fingerprint just fine. I've now re-enabled the module and all seems to be working correctly. I've reported the issue over there and linked to here for steps to reproduce, hopefully it's something that can be fixed. I'll leave this up in case anyone else experiences the same thing.
I was using lineage os 16 for about 5 months no issues whatsoever , all of a sudden fingerprint didn't work , and the option itself in settings disappeared even though I'm encrypted , backed up my data and did a factory reset , f2fs data formatted all my phone tried havoc , lineage , stock rom , the same issue over and over , decrypted then encrypted through rom but nothing change , still can't use my fingerprint to unlock the phone and I really don't know what to do , pls help!
Hello, the fingerprint sensor has a bug on a lot of P2. On mine, it worked for 5 months straight and now it's 5 months that it works just like 1 week every 5.
Rebooting, in my case, has a 25% chance of making it work again.
