Last week, the BBC's Chris Fox reported that the Pixel 4's facial recognition unlock feature works even when you're unconscious – no eyes needed.
Raising concern about the security of upcoming Pixel 4 series owners, BBC technology reporter Chris Fox tweeted earlier this week that "The Pixel 4 facial recognition works even if you're asleep/dead." In response to the worry that this tweet caused, Google told the BBC Oct 17 simply that "We will continue to improve Face Unlock over time" and that this is how the phone will go on sale next week.
