    Are ultrasonic sensors better apart from the light hing? That I have never even thought about could be a problem.
    Mine detects b between up to 5 fingers, and it’s fast and with good accuracy, which is nice because depending on the situation I may use either hand.

      They are way better, faster without sacrificing precision/security. With an ultrasonic sensor I can simply tap the screen and it’s unlocked, where with the optical ones I’d need to press for a second before unlocking, sometimes having to shuffle my finger around.

        I experienced the complete opposite. Ultrasonic was crap, inaccurate, and slow (until it stopped working completely), while optical was just a tap, and very accurate

      I went Galaxy S22 Ultra (ultrasonic) to Pixel 8 Pro (optical) to Pixel 9 XL (ultrasonic).

      My impression was the performance improved over time with the Galaxy and Pixel 8. I find the Pixel 9 worst overall, but figure they’ll improve it in software.

      No data to back that up.

      It mostly struggles when my hand is wet. I miss the Pixel 4’s face unlock.
