[SOLVED?] The fingerprint scanner disappeared

Solved: I've set the lockscreen security up on none (slide), locked the phone then unlocked it, and suddenly I got a strange notification that I didn't have the time to read, and finally the fingerprint scanner came back. Wtf
Hi everyone,
This morning my figerprint scanner stopped functionning. I don't know why, they said that the "fingerprint scanner support is not available" or something like that.
I rebooted my phone, and then it completely disappeared. I can't even find it in the settings, it's like there never was any fingerprint scanner on my phone.
What do you think?
Thanks
EDIT: also I don't know if there is any link but it seems like my phone case (the white at the back) has lose its colors at some points, like it's starting to turn grey, also around the fingerprint scanner

Fingerprint Issues

I'm not 100% sure if this is a bug or a hardware issue, but my fingerprint scanner is no more.
A while after I installed one of the nightly builds for my Axon 7 Mini, my fingerprint sensor would not read my fingerprint. It would vibrate and tell me that my fingerprint was incorrect, so it's aware that I was touching it.
So, I instinctively removed my fingerprints and tried re-registering them. When I get to the point where I enter my fingerprint, it won't do anything when I place my finger - no vibrations, no error messages. You guys think my scanner is as good as dead?

Fingerprint problems, but only on MIUI roms?

Hi,
As the title says, I'm experiencing some problems related to the fingerprint sensor, specially when I try to wake the device as I have to put my finger in the sensor twice because the phone doesn't recognize my fingerprint at the first try, it just vibrates, but the second time I put my finger it wakes up the phone with no problem. It feels like the sensor puts itself in deep sleep mode as it happens like 15 seconds after I turn off the screen.
The fingerprint sensor works fine when the screen is on, as I can unlock protected apps at the first try. But some apps that include their own fingerprint authorization like Paypal or my bank account app shows me an "error" as soon as they ask me for the fingerprint, like the fingerprint sensor is already in use (not sure how to explain it), but they work as soon as I put my finger on it.
Pressing the sensor for a little longer wakes the device at the first try, but I'm pretty sure that's not the normal behaviour.
Disabling the pocket mode doesn't help either.
As the title says, this only happens on every MIUI rom Iv'e tried, like Xiaomi.eu, Mi-global or Revolution OS, always made a clean flash. I've tried Havoc-OS and Pixelexperience and the fingerprint worked flawlessly, not a single problem with those roms and that's what makes me think that it's a software related problem. In fact, I'm currently using Havoc 3.0 and the fingerprint sensor is working great.
I've also tried to flash persist.img from the chinese official rom without success. And needless to say that I've cleaned the fingerprint sensor several times.
I know it's not a big deal of a problem, but it's driving me crazy. So any help would be appreciated as I really want to use MIUI instead of any other custom rom.
TL;DR: I have to use the fingerprint sensor twice to wake my device and feels like the fingerprint sensor puts itself on deep sleep mode or that it's already in use somehow. But it only happens on MIUI roms.

Fingerprint scanner not working on AOD screen S20+

Hi, all.
I have S20+
When the screen is off, if I touch the lower half of the screen,
a) the AOD clock doesn't show up,
b) I am unable to use fingerprint scanner on AOD screen (it works fine on the unlock screen)
Oddly, while on AOD, when the touch the upper half of the screen, AOD clock shows up, but unable to use fingerprint scanner.
I have done soft reboot, factory reset, still no avail.
If someone knows how to fix this, PLEASE help.

Question Issues with fingerprint sensor

I've had my phone for over a year now. Never had issues with anything.
Recently when I tried to unlock the screen with my finger it didn't recognise it. It was vibrating but saying that fingerprint is not recognised. I thought the screen is dirty so I wiped it - didn't work. Then I thought I have cuts on my finger so I tried to add new fingers but it doesn't work... Fingerprint sensor lights up but it's not vibrating and not scanning my finger.
I've tried resetting my phone and still couldn't register fingerprint. I've reset it again and it worked! But only for 2 days... Now again the fingerprint sensor doesn't work.
I'm on LE2123_11_F.75
Has anyone experienced something similar? Just wondering whether it is software or hardware issue?
Depending on where you bought your phone, it usually comes with a warranty 2 or 3 years.
Try log a case with OnePlus directly.
