Google in no rush to fix Pixel 4
 

Face-unlock security fix months away

The Pixel 4 is shipping with a face-unlock security issue that's not expected to get fixed for quite some time.

The Pixel 4's face unlock doesn't look for the user's eyes so that the phone could be pointed at a sleeping or unconscious owner and unlocked without their consent.

Google said in a statement that a fix requiring a user's eyes to be looking at the device "would be delivered in a software update in the coming months".

The Pixel 4 was announced last week, and instead of including a fingerprint reader as most Android phones do, the Pixel 4 features Google's newly developed face-unlock system as the only biometric option.

In principle it is not a bad system – IR dot projector blasts a grid of invisible dots onto the user's face, and a camera (a pair of cameras, in the case of the Pixel 4) reads the user's face in 3D. What is worrying is that Google was aware of the problem when Pixel 4 shipped. Screenshots of pre-release builds of the Pixel 4's software showed an option to "require eyes to be open".
