Google’s Pixel 4 will get an option requiring open eyes for face unlock

Google’s Pixel 4 uses a new face recognition system to unlock the phone but it doesn’t require the device owner’s eyes to be open, causing security concerns as anyone can grab the phone and point it at the owner’s face to access potentially sensitive information. Thankfully, this won’t be the case for long as Google said a forthcoming update will add an option remedying the issue.

Instead of sticking with a traditional fingerprint sensor, Google opted for a facial recognition system on its latest Pixel 4 and Pixel 4 XL smartphones à la Face ID on Apple’s iPhones. It can be used to unlock the phone, but it also meets certain security requirements that allow it to access sensitive apps — like banking apps — and authenticate payments.

But unlike the iPhone, which has a toggle to require a person’s eyes to be open to unlock the device, Pixel 4 reviewers, including yours truly, quickly realized the phone will unlock even if a person’s eyes are closed. Anyone — friend or foe — could easily pick up your phone, point it at your face, and if you’re sleeping or you forced your eyes shut, it wouldn’t matter as the phone would unlock.

Google is addressing this issue in an update, arriving in the “coming months,” and it will add an option requiring a user’s eyes to be open to unlock the phone — just like on the iPhone.

“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,” a Google spokesperson told Digital Trends. “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 is resilient against invalid unlock attempts via other means, like with masks.”

The temporary solution Google is talking about is Lockdown mode, a feature baked into Android 9 Pie that disables all biometric authentication methods and requires the input of a pin, pattern, or password to access the device. It can be quickly accessed from a phone’s volume menu (tap on the volume buttons), but you’ll need to toggle it on first. To do so, go to Settings > Display > Advanced > Lock screen display and toggle on Show lockdown option.

You’ll now see an option to quickly lock down the phone in the volume menu, and anyone trying to access the device again will need to add a pin, pattern, or password, depending on what you’ve set as your secondary screen lock method.

The Pixel 4 and Pixel 4 XL are Google’s latest phones, announced at an event on October 15 alongside several other Google products. The phones start at $799 and $899, respectively, and go on sale on October 24.

Have one of these Google Pixel phones? You’re getting Circle to Search

Circle to Search — Google's excellent search tool that debuted on the Samsung Galaxy S24 earlier this year — is about to become available to more people. Specifically, it's coming to a bunch more Pixel devices, giving even more people a chance to use it for themselves.

As the name implies, Circle to Search allows you to circle or scribble anything on your screen to perform a Google Search for it. It's great for those times you see something on your phone and want to know more about it, but aren't sure how to type out a Google Search for it. It launched on the Galaxy S24, S24 Plus, and S24 Ultra in January and then quickly made its way to the Google Pixel 8 and Pixel 8 Pro.

Google Pixel 9: news, rumored price, release date, and more
Front and rear profile of leaked Google Pixel 9 renders.

The Google Pixel 8 and Pixel 8 Pro are Google's latest and most powerful devices, but it won't be that way for long. Rumors of the Google Pixel 8a mean this pair of flagships will be supplanted as the latest Google phones fairly soon — but they'll be able to hold on to the title of "most powerful" for a little while longer. The Google Pixel 9 range, while definitely on the way, isn't due to arrive any time soon.

But when it does, it's sure to be a pair of blockbusters. Leaks for the Pixel 9 family are a little thin on the ground at the moment, but it seems as if Google is planning on making some big changes this time around. If leaks are correct, we expect a new look and some exciting new AI features that go beyond what we've seen before.

We have some bad news about the Google Pixel 9
A render of the Google Pixel 9 smartphone in black.

When the first wave of Google Pixel 9 series leaks arrived on the scene a few weeks ago, what really got us excited was the camera upgrade for the entry-level model. The leaked renders envisioned a triple-lens rear camera setup for the Pixel 9 that added a periscope-style telephoto snapper at the back alongside a radical design change.

Well, it seems those changes will remain a pipe dream, at least in 2024. OnLeaks, in collaboration with 91Mobiles, has shared alleged renders of the Pixel 9, claiming that the triple-camera devices in those leaked renders actually depicted the pricier Pixel 9 Pro and a new Pixel 9 Pro XL variant.
