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
  
  You probably used some cheap crappy chinese knock off ultrasonic then, because they do work, and much much better than optical
  
  Yeah, a "cheap" top tier huawei p30 pro that cost about 600$ when it was new 😆
  I dont think ultrasonic can be better, but regardless of sensor tech, in screen sensor is absolutely crap, i put the inventors to the same box as the inventors/pushers of micro usb, curved edge phone screens, removing jack connectors, etc... these things arey very annoying, and very useless.
  
  I have the P9p and have more issues with the (ultra sonic) sensor than I did with the (optical sensor) on the previous P8p.
  I even compared both in hand before trading in the older phone and the P8p scanning was much better.
  Though I have to mention; to improve the optical sensor reading I had to do 4 fingerprints with different brightness for each scan, and that what helped a lot.
  Too bad I can't do the same with the Ultrasonic sensor since it doesn't care about the brightness on the screen.
- 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.
  
  Pixel 9 pro struggles with my finger scan if it's too dry. I guess washing hands removes the body naturally produced oil and that makes it harder to scan.
