I had two Samsung flagship phones, one (S20FE) had an optical fingerprint reader and the other (S22) had an ultrasonic one. Both of them somewhat regularly failed to read my finger, were slower than a fingerprint reader on the power button and are more expensive/complex to build. They won’t work with cheap 3rd party screen replacements and some screen protectors as well.

Meanwhile my $90 Android phone has a fingerprint reader on the power button. It never fails and I never have to perfectly place my finger on the sensor area to get it to work. It just seems like the perfect place to put a fingerprint sensor, so why do phone manufacturers keep using in-display fingerprint readers over the cheaper alternative?

    It’s much better to reach. I’ll never buy a phone again without finger print reader below the screen. On my S10 it’s also very reliable. It works 95 of 100 times and those 5 times my finger was just weird on the screen and not centered.

      I loved the Pixel 4 I had with the reader on the back. My finger was already there when I picked up the phone, and it was way more accurate than the one on the screen of my 6.

      Miss that phone, except for the nightmare charging port.

      I will admit when I went to the Dark Side I was shocked by how much I like Face ID. I do miss having the in-screen fingerprint reader when I’m wearing a mask, SOMETIMES, but even that has improved in the time I’ve owned an iPhone.

      But yeah, on my OnePlus 6T McLaren Edition and OnePlus 7T Pro 5G McLaren Edition (damn I loved those phones so much) the in-screen reader was excellent.
