Android 16 lets you use Pixel 9's fingerprint sensor while the screen is off

Android 16 DP2 introduces a new feature called 'Screen-off fingerprint unlock' that allows users to unlock their Pixel devices using the fingerprint sensor even when the screen is off. This feature appears to be exclusive to the latest Pixel 9 series due to its ultrasonic fingerprint sensor technology as opposed to the optical sensors used in previous models.
