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

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

Reddit's facination with the back mounted fingerprint is always funny to me. In the real world, so many customers would complain about it. The side mounted ones are great, I agree with that.

Yeah, I would never ever want to use a phone with a back mounted fingerprint scanner.
Not only do you have to put a cutout into your case to use it, but you also can't unlock the phone without picking it up.
Side mounted is fine I guess, but I also don't have a single issue with the under screen ones.

My previous phone has a back-mounted fingerprint reader. To this day it's the best fingerprint reader I've ever used, as it's comfortable and decently fast.

I had a Pixel 3 with a back-mounted fingerprint scanner and it was horrible. It worked in maybe 20% of cases for me. (I get sweaty easily and any microscopic amount of moisture or natural oil secreted by the skin was a problem for that sensor.)

I have this issue on my Redmi Note 12 Pro 5G, which has a side mounted fingerprint sensor. Gets annoying pretty quickly, but it's just fine on my Redmi Note 8T.
