In-display fingerprint sensors have become commonplace in virtually all Android smartphones, for better or for worse, and five years later…
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.
