Fingerprint Sensor Stops Working

I've been using the fingerprint sensor on the 5X to unlock the device since I received it on the 21st. Today, my phone suddenly stopped recognizing my fingerprint. I went through the following steps:
Restarted the device.
Deleted my fingerprint and tried readding it, but it wouldn't recognize it there either.
I tried adding all my other fingers with no luck.
Had my girlfriend try her fingerprint (which she added yesterday).
Restarted the device again.
I'm hesitant to reformat as I'm happy with my device setup and I'm hoping there's a less destructive fix. Am I the only one with this issue? Any suggestions?
It's also worth noting I've made sure the OS is as up-to-date as possible.
Are you using a screen off app? I was using Screen Off and Lock through a gesture on Nova Launcher and because of it the finger print scanner didn't work. Seems to be a problem on any of those apps.

Good suggestion bsinc1962, screen off and lock / other lock screen app, causing smart lock (trustee face ) not working
in nexus 5.

Fingerprint gesture unresponsive.

Hello everyone, I bought my lenovo p2 last year and it was all working fine but for the past couple of months I have been facing some problems with the fingerprint gesture. Whenever I use it, it works fine for a few minutes but gets unresponsive after a while and when I touch it, it doesn't respond and sometimes I have the drag to the right to get it working. Is there any way that I can fix this? Thanks.
Facing the same problem but I think it can be made right to some extend by deleting the fingerprints and re-registrating would fix it
Mine is the same case too. My fingers leave marks on the scanner making it think that i didn't lift my finger up. Had to wipe it off everytime before using. Started happening aftet leaving stock rom.

proximity sensor calibration

Anyone else experiencing proximity sensor issues with the SM-A520 (A5 2017) either with stock ROM or Lineage OS 14.1 ROM? Since flash over to Linage 14.1 (from stock), the screen does not reliably go, or remain, black when held up side your face while on an active call. Cheek touches result in inadvertent button pushes. Downloaded an app for that and it re-calibrates the phone each boot (non-rooted). Now the proximity sensor works quite well.
Anyone else having the issue?
Any better "answers" than a non-rooted third party app.
Kind regards,
/S
I have the same issue. A5 2018 Oreo Stock ROM but as far as my memory serves me right the issue occured on Nougat as well. It looks like the proximity sensor is too sensitive... is there any tool so that we could calibrate it without any third parties? What solution works for you, s2scotty?

Iris scan wont work

So just venting, but new Tmobile s4 wont register the Iris scan. It looks very badly out of focus and never adjusts to the eyes. Any others having this issue?
Same for me! But it registered my eyes before I put on a milky display protector with cutouts for the 3-4 sensors on top.
Don't know if this is the trigger for my problems, but I reseted my biometrics yesterday and can't get iris working again...
Any way to clear data for the biometrics app?
Works fine for me.

Been having this issue too... Just got my device today and Iris scanning doesn't work... Is the preview supposed to be blurry when trying to register? I haven't applied a screen protector or anything and nothing is installed on mine as far as I'm concerned

Annoying lags to wake up or unlock the screen

Since few days on my redmi note 8t (stock miui11) I'm facing annoying lags when I try to wake up the screen moving the phone from its position. At the same time the fingerprint reader seems to be not responsive, for some seconds (about 4/ secs).
It seems like the phone was in deep sleep with difficulty to wake up. I don't know if it's a problem of miui or a problem due to some hw issue (like for example proximity sensor).
