For some, the snazzy new face unlock system on Google's latest Pixel 4 is a whole lot less convenient than it should be. Google Pixel 4 has got some user-facing issue and this time it is with Project Soli-backed face unlock system. Once the Pixel 4 was launched, users discovered that face unlock had one critical flaw when compared to Apple's, as it didn't have a Require Attention option - that someone could unlock your phone by holding it against your face while you sleep. It shows this error "Can't verify face, try again" when the user try to use the biometric authentication in the Pixel device. In this case, the user kept getting a message after the update that face unlock might stop working and re-enrollment was needed. Although there are reports of the issue at venues like the Pixel support forums, Reddit, and the XDA Forums, with some threads around 20-40 comments deep, the problem doesn't appear to be particularly widespread. Hardware not available" and "Can't verify face.
The problem first popped up starting around November, escalating in frequency over more recent months.
For some users, they abruptly started receiving system notifications asking them to re-register their face again, despite the face unlock functioning fine. Some users report they can't even remove the registered face data, GSMArena reported on Friday. Deleting and setting up face data again hasn't worked, nor have simpler solutions like rebooting the phone. The issue doesn't seem to have resolved also after resetting the smartphone in safe mode. The issue reportedly pops right back even after doing factory reset. Some users have even tried to factory reset their device but it has not always been successful. The problem is, the owner of the device can't take a backup of the system like a fingerprint sensor.
