Xiaomi mi 9t pro face unlock doesnt work - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

Problem
Face unlock is not usable because it cant add face data at all. Error is couldn't add face data.
It doesnt matter what permission u set on or which data you clear or even if u do a hard reset the result is the same. It wont work. Now because i already fixed the issue of no region change waiting for so called mi support and for someone to acknowledge the problems in xda in waiting for respons im thinking i will fix this one as well.

I have the same issue
Tried a lot, all failed

What the stupid third party rediscovery. It seems that face unlock doesn't work because remove animations is active in settings in accessibility. As soon you turn off remove animation. The face unlock works as it should.

[Q] Keeps requiring password/pin

Ever since the update to Oreo I've been constantly having this issue and it's extremely irritating and can't figure out how to stop it from happening. Basically at least once a day now, sometimes more than once it refuses to use the fingerprint scanner and wants me to enter my password or now my PIN since I switched to the less secure pin just to make it less of a pain everytime this happens and I just want it to go back to working properly so I can have the password again, does anyone know how to fix this issue? It's an unlocked note 8 and it's not rooted or anything, just a stock phone.
It's probably because you're phone has restarted and requires a pin after a restart before it'll use biometrics - It's a problem on Oreo, it's basically just a completely cr*p update that's broken so many things.
Samsung as usual, don't seem to give a stuff!
Nope, it's not a restart that's causing it, that's an entirely different message, especially since the phone's encrypted so the phone won't even start up on a reboot till the encryption password is entered. This is just a it randomly won't accept the fingerprint to unlock, I've turned the phone off then turned it right back on to unlock it and this has happened, 100% certain it had nothing to do with rebooting.
I've read some people saying they had an app that force locked the phone and that causes this and removing it fixed the problem, but I don't have any app that does that.
I have an unlocked note 8 too, I only use iris validation (finger print does not reliably work for me because of my eczema), the only time i have ever encountered this was when the phone went to lock screen while trying to access bio-metric validation (banking app, only ever happened once, i disabled fingerprint after due to unreliability relating to eczema as previously mentioned)
Maybe not the same issue but fingerprint unlock never works for me reliably. I get that message when my fingerprint can't be recognized. I have working hands so often my fingers get knicked, scratched, etc or even just wet causing my fingerprint not register. If I reregister fingerprint with out a perfect fingerprint, after my fingers heal, can't be recognized again. Happened on my Note 5 as well so I stopped using fingerprint to unlock.
Don't think that's the issue for me, I never have any issues with the fingerprint reader normally, it always works great when it actually lets me use it.

Annoying Pop-Up each time I use fingerprint to unlock my phone.

Hello,
As the title says, I get the pop-up attached to this post each time I use the fingerprint to unlock my device. It appeared one hour after I installed an app called light flow. It doesn't happen when I unlock it with my pin, it only happens with my fingerprint AND when my WiFi is off. I Did a virus scan and of course it came up with nothing. I need help cause it is annoying the hell out of me.
Thanks.
Ok so I came across this:
https://forums.androidcentral.com/g...8-annoying-wifi-scanning-popup-wont-stop.html
Which basically says that disabling WiFi+ will work until Huawei and Google fix the Google play services bug.
Thanks for nothing:highfive:

Smart lock doesn't work after october update

I can't access smart lock menu. I write the password needed to enter and the page is white. Anyone else having this issue?
Same here.
Same here. Someone knows the solution?
Disable trust agent (smart lock), reboot, enable it again
It happened before, but what is weird is that is fixed in the 2nd october update (9.6.15) at least for me and a bunch of people that have confirmed

"Disable trust agent (smart lock), reboot, enable it again"
Thanks. That works in apdate 9.6.15.
The solution above is valid, but everytime you need to restart the phone you'll have to disable it and turn it on again when the phone is on. Otherwise it's gonna bug everytime you restart the device. This happens to me.

Question Face recognition/unlock stopped to work after last update

Hello! After the last update that I've received a couple of days ago (current OS version: 31.1010.0410.61) I can't unlock my phone using the camera, I need always to use the fingerprint. I've tried to re-setup the face recognition but nothing, I can't unlock the phone using the camera. Any idea how to fix it? I've noticed also that before during the unlock there was the green camera icon on top right, now there is just a green dot. I don't know if it can be relevant.
Any suggestion is appreciated.
Thanks!
Try to - delete your face from phone. Then in apps find Asus Face Unlock Service - force stop, then clear internal memory. Restart phone - register face and boom - works like charm, at least for now. You can also clear cache files system-wide and reboot your device.
Thanks for the suggestion but at the end I've solved in another way. When I went to "Security & Lock screen" section to remove the face recognition. I've noticed that there was a "Google Play system update" pending.
I've launched it and it fixed it
Good to know. But it may be temporary fix. I reported this bug of Asus official forum and - one of mods reply that they fix this in next FOTA. This must be something more serious.
The problem came back, after about a day later. Now everything is updated but the unlock doesn't work anymore. I wanted to try your method, but I don't find any "Asus Face Unlock Service" app. In the meanwhile I'll hope in a fix in the next FOTA

When you enter all apps menu press three dots and select show system apps. Then you find Asus face app.
Edit.
For me this solution is working for a out 2 days. After app crashes and you need repeat whole process.
I've just noticed that if you restart the phone it also "fixes" the problem, but I suppose that it won't last long. I really hope that they fix it asap

Question Fingerprint scanner not working

Hey everyone,
I was listening to music on Spotify last night on my Redmi Note 10S. I then turned off my phone and when I tried unlocking it, the fingerprint scanner wouldn't detect the fingerprint. I tried to make another fingerprint in the settings but it would not do anything. I thought it must've been a small issue and decided to restart my phone. Still Nothing. I need some ideas as to how to restore fingerprint functionality at home as I don't want to take it to a service center again.
If you have a solution please let me know.
Thanks!
