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.

I’m excited for the Google Pixel Fold, and you should be too

It’s official: the Google Pixel Fold is coming. After months of rumors and speculation, Google revealed the Pixel Fold on Star Wars Day, of all days. With the tagline “May The Fold Be With You,” Google dropped a tweet that showed off the Pixel Fold in all of its glory. And now, after the official announcement at Google I/O 2023, the Google Pixel Fold is shaping up to be one of the more exciting releases this year.

I’ve always been an iPhone gal, but since I joined Digital Trends, I’ve been checking out Android phones more than ever before. I’ve taken quite a liking to the Pixel lineup of devices, including the Pixel 7 and Pixel 7a, which also just dropped today. But the Google Pixel Fold is the one device I can’t wait to get my hands on, especially when compared to the competing Samsung Galaxy Z Fold 4 (and the Galaxy Z Fold 5, which is likely coming this year too).

While the technical specs of a phone play a large part in the decision-making process of picking up a new device, how it looks can be equally as important for many people.

The Google Pixel 7a is Google's latest addition to its midrange A-series smartphones. It's likely to be one of the best options for anyone who wants a strong handset with pure Android, solid performance, and an exceptional camera.

But we can't touch on the hardware without addressing one of the most common questions about any new smartphone. Namely, does the phone have a headphone jack? Smartphone manufacturers have been on a crusade against the venerable port in recent years, and the headphone jack has been excised from the vast majority of the phones you can buy today. So, does the Google Pixel 7a include a headphone jack, or will you need other ways to listen to music, audiobooks, and podcasts?
