Some users report that Face Locking stopped when the Pixel 4 was updated to Android 11, but not for everyone. Some have been reporting problems for months. Others have speculated that this may be linked to a previous device sensor problem, citing as much evidence as possible data shortages in proximity and circulating light sensors.
Google is not sure if there is a solution to this latest Pixel 4 Face unlock issue. Although there are hints that it has addressed the black bar alerts with the November Android update, owners are still complaining about issues even after the patch is installed. The release notes do not mention anything specifically addressed for face verification.
