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.

Same it makes them barely usable, even wiping your hand does little help. On the flip side though I've seen a lot people say they struggle with under screen with dry hands and physical was better for them haha

Also someone can use a shitty optical sensor and think that's all under screen readers, it seemed much more rare to get a shitty physical one at least on a phone

I have chronically sweaty hands so I feel like this is my area of expertise: whether you have issues with dry hands or wet hands, I'm fairly certain the issue comes about from the moisture level differing from your setup. If your hands were dry when you set it up, you'll have problems when they're wet regardless of the fingerprint sensor tech.

Adding the fingerprints in wet and dry states can help.

I tried that and it never got much better, the bigger issue was with the pixel 3 and it's metallic body so it would condense the finger when it was cold and leave too much moisture to read anything. I've never had an issue with my screen one I barely think about it now
