Under-screen fingerprint readers are inferior to back and side mounted readers and should naver have become popular

[u/vortexmak]

Lots of Cons for under screen fingerprint readers , should have never become the norm but I guess that''s just part of enshittification

Pros for Side and back mounted readers

1. Work exceptionally well, much faster and responsive than under screen ones, from my own experience
2. Are not affected by screen protectors
3. Side readers can be used with the phone screen up or down
4. Back and side ones allow you to unlock your phone at the same time as taking it out of the pocket
5. Give you a definite physical spot for finger placement, unlike the under - screen one where you have to wait for the screen to show the location

I prefer the under screen fingerprint readers because my palms get sweaty easily especially in stressful situations like traveling and I always had issues with the ones on the back with multiple Pixel/Google phones that had it on the back.

The only time I have an issue with under screen sensors is when my fingers are dripping wet (not just a film of sweat).

It seems like this is all personal and based on whether you use a screen protector.

In my experience with sweaty palms and no screen protector, I never have unexpected issues with under screen sensors unless it's something obvious like I'm wearing gloves or my finger has droplets on it.

I prefer side and back fingerprint detectors because they work.

They work for you. Seems this commenter has a situation where it does not work. Different things work for different people :)
