Pixel 4 and Pixel 4 XL will be available in Clearly White, Just Black, and "limited edition" Oh So Orange colour options.
The problem was first noticed by technology reporter Chris Fox, who tweeted that the Pixel 4 he was using could unlock even if his eyes were closed. But this feature comes with a major flaw, as it could unlock the phone even if users were not looking at it.
Still, if you're really anxious about security on the Pixel 4, or any phone for that matter, nothing seems to beat the good old-fashioned PIN or passcode.
However, the big news here is Google's claim that the facial recognition tech on the Pixel 4 is the fastest in the industry. The sensors sense when you're about to pick up the phone and turn on the face unlock, so it's ready and waiting.
The only workaround for this is turning on lockdown on Pixel 4.
In leaked images obtained by The Verge this month, the Face Unlock settings page included an option named "Require eyes to be open", which would have prevented a third-party from unlocking a device while the owner was asleep or out cold. The easiest example is pointing a phone at a sleeping person to unlock it. When in fact there are tons of exciting new AI and machine learning features, camera controls, and cool things the Pixel 4 has to offer.
Other face lock systems, like Apple's Face ID, have an alertness check that looks for open eyes.
The Google spokesperson also told Business Insider that "Pixel 4 face unlock meets the security requirements as a strong biometric, and can be used for payments and app authentication, including banking apps". It also introduced iris scanning support. When a Pixel user starts to reach for his phone, the movement is detected by the Soli chip and Face unlock is turned on. Plus, according to the Verge, Google has said that the design of the phone will improve as time goes by with software updates.
