Google debuted infrared (IR) based facial recognition tech with Pixel 4 series which works similar to Apple's Face ID. It makes use of the IR sensors and front camera to create and recognize the depth map of the user's face. It is a very secure facial recognition tech but with a minor flaw i.e. it can unlock the phone even when the eyes are closed.
As you would expect, it was reported and shared by the whole tech community last week. Google has heard those talks to and has finally offered an official statement on the situation. It has assured that Pixel 4 face unlock will receive an update with eye detection support. It will ensure that the tech checks if the user's eyes are open before proceeding with the phone unlocking. The only issue is that this particular update is said to arrive in the "coming months".
Here is what Google has said officially:
"We've been working on an option for users to require their eyes to be open to unlock the phone, which will be delivered in a software update in the coming months. In the meantime, if any Pixel 4 users are concerned that someone may take their phone and try to unlock it while their eyes are closed, they can activate a security feature that requires a pin, pattern or password for the next unlock."
It is hard to say when exactly the update will arrive but it is safe to assume that the change will not take place anytime soon. This is the reason Google is recommending using alternate options like keeping the phone safe as a workaround. One of these options is to use the Lockdown functionality of Android. It is a feature that temporarily disables the biometric authentications (face unlock for Pixel 4) and will require the user to use other authentication methods like a PIN or a password.
