Why do phone manufacturers use in-display fingerprint readers instead of fingerprint readers on the power button? - Lemmy.ca

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 to build. 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?

I don’t understand why “FaceID” isn’t more of a stardard on Android. I remember people online complaining when Apple got rid of TouchID on their phones, yet anyone who use FaceID quickly forget that fingerprint skanners are a thing. It works so fast and you don’t have to complain about where a sensor might be on a device, if you can see the screen the screen the device is unlocked.

Because you could unlock anyone’s phone with a photograph of their face.

Ah like in the movies!? I saw a movie where they got someone’s pass code by watching them type it from a satalite, trough a windows 😅

It’s not how any of those work.

Try reading one of these some time instead of being a pretentious dumbass dipshit:

To bypass FaceID depth check you simply wrap a photo around a foam mannequin head and ensure the eye sockets are darkened and the lips around has depth and it will work.

The face-unlock feature on nearly half of late-model Android phones can still be fooled by photographs, a Dutch study has found.

Fair point, however None of those are FaceID by Apple, all links are Android in either title/link or subtitle on the page. You did answer by question: why people don’t use face unlock on Android is they are horribly implemented vs FaceID on iPhones, so I will apologize for being pretentious!

Fair point, looks like I’m the dumbass dipshit now.
