FACE ID IS NOT WORKING PROPERLY

Hello, Fariz240.

Thank you for using Apple Support Communities.

I understand you're having issues with setting up Face ID. I'd be glad to help.

Start first by making sure that you are running the most recent software version on your iOS device. As of this writing that is iOS version 13.4.1:

Update iOS on iPhone

Next, check to make sure that your phone is set on ring and not silent:

Then, restart your device:

Restart your iPhone

Afterwards, try enrolling in Face ID once again, for at least a full minute.

Let me know how this goes.

Cheers!
