Imagine having to fumble with your phone’s power button or swipe to wake the screen just to unlock it—a small inconvenience, but one that adds up over time. Well, Google just quietly fixed this annoyance for Pixel users with the latest Android 16 update. Here’s the scoop: the Screen-off Fingerprint Unlock feature, which allows you to unlock your phone with a fingerprint even when the screen is completely off, has made a surprising comeback. But here’s where it gets controversial—not all Pixel devices are getting this treat, and the reason might lie in the type of fingerprint technology they use.
TL;DR
- The Android 16 QPR2 update reintroduces Screen-off Fingerprint Unlock for select Pixel devices.
- The feature was initially available in Android 16 DP2 for the Pixel 9 series, then mysteriously vanished in later betas.
- It’s now back for the Pixel 9 and newer models, but older devices like the Pixel 8 Pro and Pixel 9a are left out.
Google’s latest update is more than just a routine patch—it’s a subtle yet significant win for Pixel users who’ve missed this convenience. The Screen-off Fingerprint Unlock feature first appeared in Android 16 DP2 for the Pixel 9 series, but its journey has been anything but smooth. After being unexpectedly removed in subsequent beta builds, it’s finally back in the stable QPR2 update. However, it’s not a universal return; only Pixel 9 and newer devices are seeing the feature, leaving older models in the dust. And this is the part most people miss—the reason might boil down to hardware differences.
Reddit users have been quick to notice the feature’s return, with many Pixel 9 and newer owners confirming its presence in their Fingerprint settings. However, the Pixel 9a and older models like the Pixel 8 Pro are notably absent from the party. We’ve confirmed this on our own devices: our Pixel 10 Pro XL has the feature post-update, while our Pixel 8 Pro does not, despite running the latest software.
Why the exclusion? The most plausible explanation is the type of fingerprint scanner used. Pixel 9 and newer devices feature an ultrasonic fingerprint scanner, which uses electronic pulses to detect fingerprints even when the screen is off. In contrast, older models, including the Pixel 9a, rely on optical scanners, which often need the display’s light to read fingerprints. This hardware disparity could be why Google hasn’t rolled out the feature universally—though this remains speculation, as Google hasn’t officially confirmed the reason.
Ultrasonic scanners are generally more reliable in screen-off scenarios because they don’t depend on the display’s illumination. Optical scanners, on the other hand, might struggle to function accurately when the screen is off, making the feature less practical for older devices. But here’s a thought-provoking question: Is Google prioritizing newer devices at the expense of older ones, or is this a necessary limitation due to hardware constraints?
For those lucky enough to have a compatible device, enabling Screen-off Fingerprint Unlock is straightforward. After updating to Android 16 QPR2, head to Settings > Security & privacy > Device unlock > Fingerprint, and you’ll find the toggle waiting for you. Keep in mind, though, that the update is sizable, so plan for a longer download time.
What do you think? Is Google’s decision to limit this feature to newer devices fair, or should they find a way to bring it to older models? Let us know in the comments—we’d love to hear your take on this quietly controversial return.
