Fingerprint and FaceID suddenly shuts off

[Hozyainjunior]

Hello dear community.
Recently I started getting problems with screen unlock features on my phone.
For some unknown reason, my Zenfone 8 suddenly shuts off fingerprint and FaceID simultaneously. It does not matter what I do (browse web, listen to music or even when my phone lays on a desk in standby mode), it just disables those unlock options with no error or warning.
Phone simply locks screen on its own.
I can still unlock it using pin code, or reboot device to get those features working again, but it is always temporary solution (sometimes minutes, sometime hours).
Weird thing is it started to occur when I moved to another country. Not sure if it's related or just coincidence.
Any options apart from resetting the phone?

Hi @Hozyainjunior
What firmware is your ZenFone 8 on, and have you done any recent upgrades that could have caused this? Either way, I will report to see if any other users in the other forums are facing this.
Thank you!

Is this because of having to input the pattern every 72 hours? Or is it happening more regularly?

Thanks for replies guys.
It happens much more regularly. Basically, every few hours.. sometimes even minutes.
I'm running 31.1010.0411.138
Not sure about recent update. I've installed newer version in last 3-4 weeks, but issue started before this update.

If you have faceunlock enabled it is a standard feature. It disables all biometrics after few hours of inactivity. It is beacause faceunlock is less secure than fingerprint.
