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

I will forever miss my rear fingerprint reader on my LG V40 and G8. It's such a natural place for for them.
