Some users are complaining that their Pixel 4 has a problem with the operation of facial recognition. These users are receiving error messages while trying to unlock the phone with their faces. It indicates that the face could not be verified, inviting them to try again.
The problem initially arose in November and has been spreading in recent weeks. For many users, the failure started after receiving one of the last monthly security patches, but in other cases, there is no apparent reason. Although there are quite a few users affected, it does not seem to be a problem that affects most users.
Some users have tried to do a factory reset but it has not always worked. For affected users, it is a very annoying problem since they cannot unlock their smartphones with ease.
At the moment, Google has not pronounced, but hopefully, they can fix it soon with a software update.

Google Pixel 4 problems
It is worth to mention that Google Pixel 4 phones have experienced a series of problems since they went on sale last October. Some users have reported problems with performance or with the battery. In addition, a problem that affects the screen, specifically the oleophobic screen coating of the Pixel 4 and Pixel 4XL panel, has recently begun to be seen.
The protector is beginning to deteriorate in some Pixel 4 devices. The problem has begun to appear within a few weeks and after moderate use. It could be an isolated problem, but remember that the Pixel 2 was famous in its day for presenting a very similar deterioration. It was replicated in some Pixel 3 and Pixel 3 XL devices.
