Last week, the Android 16 Developer Preview 3 (DP3) was launched for Pixel smartphones, introducing a new functionality aimed at enhancing the convenience of using the built-in fingerprint sensor. This feature enables users to unlock their devices using the fingerprint sensor even when the screen is not active. Initially rolled out with the Android 16 DP2 update in December, it was limited to the Pixel 9 series. The recent update broadens its availability to all Pixel devices equipped with an in-display fingerprint sensor.
Unlocking the Pixel on Android 16 DP3
Currently, the in-display fingerprint sensor on Pixel devices requires the screen to be awake in order to function. Although there are no direct settings to activate this feature, workarounds such as enabling always-on display or utilizing the tap-to-wake function have been employed. However, the new Android 16 update is set to eliminate this limitation.
As reported by Android Authority, the Android 16 DP3 introduces a setting called Screen-off Fingerprint Unlock accessible on all Pixel devices that feature an in-display fingerprint scanner. This new option allows users to enable fingerprint unlocking even with the screen off. Once activated, users can simply tap the fingerprint reader, which will illuminate, allowing for biometric verification and unlocking the device.
This feature is located within the Settings menu, specifically under Security & privacy > Device unlock > Face & Fingerprint Unlock > Fingerprint Unlock.
While initially introduced in the Android 16 DP2 update, the latest version expands its functionality. Testing has confirmed it works successfully on the Google Pixel 6a. Previously, the feature was believed to require an ultrasonic under-display fingerprint sensor; however, it remains unclear whether this requirement has been adjusted in the Android 16 DP3 update. Notably, the Google Pixel 9 series is the only current lineup utilizing an ultrasonic sensor, while models preceding the Pixel 6 utilized an optical fingerprint reader for secure access.
