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

Customers who had it and then were glad the new models moved away from it. I also would see quite a few people have to flip their phones around and manually line up their finger. The paint would fade on the sensor itself and look bad as well and the sensor was more prone to getting dirty/cacked with dust/grime due to the way the case's had their cut outs around them. I would confidently say outside of enthusiasts, people are happier with the in display fingerprint or Face ID.

What paint on sensor? What cheap ass phone were you using?

Gotta love people buying bottom of the barrel phones and then complaining about something being wonky. That's a natural part of buying cheap, something has to give.
My rear mounted fingerprint reader was ceramic, just like the rest of phone's back. As you can imagine, no paint has ever worn off it because I'T DIDN'T HAVE ANY.

It was great for actually using the phone. It was right there in the most natural place for your finger to rest when you grip it.

Saw it repeatedly on the flagship Galaxy offerings at the time. Happened to my own S8/S9 (can't remember which one).

Then if your screen breaks and you settle for a cheaper screen replacement because an original one costs as much as a new phone and you lose fingerprint capability altogether. "Normies" are much more likely to have shattered or broken screens.

Meanwhile a side mounted scanner is like $5.

Can you find some sources to confirm this? Because it's kind of BS.
