[–] darkstar@sh.itjust.works -1 points 2 years ago (2 children) You probably used some cheap crappy chinese knock off ultrasonic then, because they do work, and much much better than optical permalink fedilink source parent hideshow 4 child comments replies: [–] disconnectikacio@lemmy.world 2 points 2 years ago* 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. permalink fedilink source parent [–] BlueFire@lemdro.id 2 points 2 years ago* 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. permalink fedilink source parent
