Every week it seems that there is a new issue with the Pixel 4 series. And Google is then forced to play catch-up through the monthly release of functional patches. The latest bad news to hit the phones has to do with the secure facial recognition system known as Face Unlock. Several Pixel 4 users have posted on the Pixel support site and Reddit how the Face Unlock feature just broke on their handset.
The first sign that something is amiss comes via the receipt of a message to the user telling him to re-enroll his face with the feature or else Face Unlock will not work.
