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