Fingerprint cannot unlock oreo 8.0 - Android Q&A, Help & Troubleshooting

I have a problem with my May update Oreo install on a Xiaomi MIA1. I did a clean install of the OS and installed all apps and data back to the phone.
I have set up the fingerprint scanner and pattern. I now find that every time I unlock with the fingerprint scanner, The first press wakes the screen and shows the lock screen. The second fingerprint scan brings up a screen with the pattern and the words "Pattern Required After Device Restarts." as if I have just rebooted the phone. Although I have not rebooted the phone.
I know that I get asked to add my pattern (or PIN if that is set) the first unlock after reboot. It is like Android continually thinks I have just rebooted the phone when I have not.
I have noticed if I delete all lock functions, then reset the Pattern or Pin and the fingerprint, fingerprint does unlock the phone on the first few attempts and then goes back to not locking it without changing any settings.
I set up a new user, set up the fingerprint and pattern and the fingerprint also worked for a few times, then stopped working.
I do not have a third party launcher or lock screen loaded.
The fingerprint unlock was working fine before I clean installed and I think was initially working for a day or so after install.
I am aware that you must enter your pattern or PIN on rebooot... This is not what I am talking about.
Under Settings > Security and Location > Device Admin Apps only Find My Device and Outlook Device Policy is listed. Both apps are unticked.
I have no third party launcher or locking app loaded.
Can someone offer some guidance on how to fix this issue? Surely I am not the only person who has seen this issue. All other searches on the net refer to 3rd party launchers and that is not the issue I have.

Well it seems I am the only person on the web that has ever had this issue. I did a full hard reset and the issue is gone.

No it's just that oem is not very popular here and those that do develop for them would never add their finger prints to it.

[Q] 5.0.2 Screen Lock and Smart Lock

I just recently got the 5.0.2 update and have a couple of questions.
1. When I set up a pattern lock, then decided I didn't need it, I went to change it back to swipe unlock, only to find it grayed out and the message "Disabled by administrator, encryption policy or credential storage"
Tried looking through any settings I could find that related to those reasons but could find nothing that seemed to relate to resetting swipe unlock as an option. Has anyone encountered this or know how to fix it?
2, So I decided to set up Smart Lock with my home as a trusted location. But the device is still locked every time I turn it on, even though the Smart Lock setting shows my tablet at home, right in the middle of the radius of dots it says is the trusted location and I still have to go through the 2 step process of swiping on the main lock screen with the notifications on, then entering the security pattern on a separate screen then finally getting into the home screen.
Any ideas on this one?
And when lollipop comes to the z3 phone is pattern unlocking going to be a 2 step process on that as well?
Regards for any information on these questions.

Do you have an exchange account setup? I know my work email server has restrictions where I have to have a screen lock.

Currently having the same issue. Tried deactivating all device administrator but still could not revert back to swipe unlock
www dot reddit.com/r/Nexus5/comments/2mptwm/lollipop_can_not_disable_passwordpattern_to_unlock/
Does anyone know if deleting credential storage will result in any adverse effect?
Well still no joy, although Smart Lock did recognize my location once, but then 10 minutes later it wasn't working again.
And no Spectre51, I don't have an exchange account set up.
Do you have anything under Settings->Security->Device Administrators? I just removed my outlook/exchange account and had the same issue but under device administrators outlook device policy was still checked. Unchecked that and I could change it to swipe.
I know you said you don't have an exchange account but maybe something else in there is still enabled causing the issue.

MM locking with password "randomly"

so with the update to MM I'm finally able to use the fingerprint unlock with a case, but either I missed something or it's still somewhat annoying to use. after booting up I need to enter a password, which I'm okay with, however after using my device for a bit and letting it go to lock there are times where I need to re-enter my password instead of the fingerprint and this is without rebooting. is this normal?
EDIT: so I came across a few places that mention the use of Nova Launcher or 3rd party lockscreen apps... I don't have any of the latter, but I do have Nova Launcher except I'm not using that to lock my screen. am I missing something here?
It will do that I believe as a default. You can set up a smart place, like home, on your person, whatever, and it won't lock with a password. I use it on mine for the house, and certain devices it connects to.

I believe there may be an issue now... I just unlocked my device using the fingerprint and I have my device set to lock after 10 minutes. Less than 10 minutes after my screen goes off I wake up my device with a double tap and it's locked, prompting for a password!

Face unlock requies slide to unlock even if checked unlock automatically

Please help, my Huawei requies after succesfull face recognition unlock still slide to unlock with finger, even if I checked in system settings Direct unlock feature under security option. Week ago everything was OK, now direct unlock not working. Any ideas? Thank You!!!
It does that when the face unlock and fingerprint unlock conflict with each other. It happens to me sometimes.
Just try not to use both at the same time by accident. I set my face unlock to only unlock when I'm looking irectly at it.
Thank You, bazanime, disabling fingerprint unlock solved my problem. But it is still strange to me, untill now (few days ago) both unlocking methods worked together...
Thanx again for help
This happen to me when i have finger print snd face unlock activate, and try to unlock with finger print and fail. In that case always recognise mi face but I have to swipe up to unlock 100%, dont know why either

You're welcome, Happy to help. Though I wouldn't turn off fingerprint unlock because it still good, just in case your face is not recognised. Just use the face mostly.

Try the following solutions to resolve the issue:
go to your Settings > Reset > Reset all settings . This will reset all settings, no data or documents will be deleted. Reboot your phone into recovery mode (press and hold the Power and Volume Up buttons simultaneously ) and use it to delete cache partitions (select Wipe cache partition) . Finally select Reboot system now.
Good Luck
Try turning off do not distrurb
It only does that to me when I lift my phone and it doesn't initially unlock with my face, so I mash my thumb onto the screen only to get blinded by the icon showing around the edges of my thumb putting out more lumens than Tsar Bomba, which triggers an epilectic fit of apoplectic rage during which I smash the phone repeatedly into my face and attempt to put either of my thumbs *through* my phone over and over again. That's the only time I see that.
This was hapening to me too !
My mate 20 pro always worked with facial recognition every time but recently worked intermittently, I tried all the usual reset and wipe cache partition, then I thought that the only thing I had changed recently was that smart lock and trusted place was on as I noticed that away from home facial recognition would work but at home it would say 'smart lock recognition successful slide to unlock' even though the phone was set to direct unlock - changed it, now problem it solved so maybe check this.
Update 9.1 solve this issue .. now it is much faster
I already updated to 9.1 but problem still existed, smart lock and turn off trusted place was definitely my problem.
The earlier mentioned "smart lock at trusted place" will ruin the face unlock.
NOTE: Even if the smart lock is OFF, it will interfere if you have some location saved and you are trying to use the face unlock in there. So you need to delete the "trusted place" from the smart location.
Simply turning off Bluetooth worked for me

Unlock Screen Issue

So I have a LG ThinQ 8 that belongs to a friend. They said they reset it trying to fix some freezing issue. When it came back up he set up a finger print then decided to try a pattern. He can't get the pattern to work. If it asks for his fingerprint he enters it and its fine but it immediately takes him to the pattern. Is this a LG pattern addon or something he has downloaded? I can't even power off the phone without the pattern. Any good suggestions on fixing this?

Question Lock screen asks for pin

Hi,
I am using fingerprint sensor and smart unlock but several times a day and every morning the phone is manually locked and I have to enter my pin again. Is there a setting I am missing here?
same here. also it keeps asking pin through the day!
also I'd appreciate if I won't need to confirm pin once is entered correctly (just numbers then unlock instantly)

Is it that your phone is rebooting? There have been people reporting random reboots with their devices ..

Thats true, the extra confirming is annoying as hell...I think smart lock introduced this issue, so I will try to turn it off for now...

I have not noticed any reboots yet but I dont think that the problem. I still see notifications on the lock screen. I believe that would not be the case if the phone rebooted.

Smart lock relocks after 4 hours of inactivity and apparently defaults to PIN or Pattern, not FP.

That explains it, but it is not smart at all :-/

Doesn't seem to matter whether it's active or inactive. It seems to re-lock and require a PIN every 4 hours.
Extremely annoying. SmartLock on my Samsung phone didn't behave like that.
Disabling smart lock fixed it for me, make sure are smart lock triggers are gone

So now it is always locked and the FP is the default? I like having it unlocked at Trusted Places for 4 hours better.

I might just try this. I used smartlock on my Galaxy s20 FE because the fingerprint sensor was way down at the bottom and was difficult to reach, so I would just press the power button and swipe up on the screen.
However, I discovered with the Pixel 6, that when it's smart locked, if you just touch the fingerprint sensor icon, it turns on the screen and opens the phone. (without it actually triggering the fingerprint sensor) No pressing the power button or swiping required.
So I've started getting into the habit of just pressing the fingerprint icon anyway, even when it's unlocked with smartlock. So, as long as the fingerprint sensor is reliable enough, I don't really need the smart lock. I would be doing the same motion to unlock it with the fingerprint. (Although it will be a little slower and possibly a bit more unreliable)
Well, I don't think it's smartlock related. I turned off smartlock a half hour ago and used the fingerprint sensor to unlock it several times since then, and then a couple of minutes ago, it forced me to enter the PIN. Almost exactly 4 hours after the last time I had to enter a PIN.
I was wondering exactly the same... it's a weird behavior.
I think it may be a 'feature'. A fingerprint is considered somewhat less secure by Google. Ironic, given on a P6 it seems to lock folk out a lot of the time!
Understand fingerprint security - Pixel Phone Help
Your fingerprint data is stored securely and never leaves your Pixel device or Nexus phone. Your fingerprint data isn't shared with Google or any apps on your device. Apps are notified only wheth

As you say, annoying though.

Did you reboot the phone after changing the smartlock setting? Perhaps the phone has held onto that setting in memory.
i am having the same nightmare here. Considering i am wearing gloves most of the time, i need to usesmart unlock. but then every few hours i need to type pin, plus i need to press entre. it really breaks flow here

Smart lock resets every four hours, which requires you to enter your PIN to unlock for another four hours.
Confirming a pin makes it more secure, as now the number of digits in your pin is also hidden. In theory, this would make a 4 digit as secure a as 10 digit one as a potential thief would not know which to try.
