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.

Google has just announced the next Pixel A-series device -- the new Google Pixel 8a. The A-series is the more budget-friendly Pixel option, and it comes out halfway in the cycle to the next mainline Pixel device.

This year, the Pixel 8a offers some big upgrades over its predecessor, the Google Pixel 7a. It’s also more similarly matched with the standard Pixel 8 and Pixel 8 Pro, both of which came out in October 2023.

The Google Pixel 8a is official. Here’s everything that’s new

A week ahead of its annual developers' conference, Google has dropped a new budget phone in its Pixel-A series. The Google Pixel 8a retains the line’s signature look with a horizontal camera island at the back, but serves it in a package that embraces rounded corners and also happens to be fractionally smaller and lighter

The most meaningful changes are reserved for the display, silicon, and battery. The OLED screen’s size remains the same at 6.1 inches with a resolution of 1080 x 2400 pixels. However, the refresh rate has been increased to 120Hz, up from the Google Pixel 7a's 90Hz display. This HDR-ready panel offers a peak brightness of up to 2,000 nits and also features a fingerprint sensor underneath.

Google just launched a new Pixel Tablet … kind of

With the excitement of the Google Pixel 8a launch, it might have passed a little unnoticed that Google also launched a new Pixel Tablet — though not exactly. For one thing, the “new” Pixel Tablet is the exact same device as the “old” Pixel Tablet. We mean that literally: same specs, same look, same screen. The only difference with the newly launched Pixel Tablet is that it’ll be sold without its charging/speaker dock, unlike the previous model, which included it.

At $399, the new Pixel Tablet is $100 cheaper than the earlier model, but that’s to be expected — both because it doesn’t come with any hardware refresh and also because it cuts the dock. It's also worth noting that it will not be launched with any new first-party accessories like a keyboard or stylus, which were previously rumored for the tablet.
