Some trends really don't make sense to me.
1) When my phones mounted in the car, it makes it a lot easier to unlock vs the back
Counter point: You can and probably should set your phone to unlock by it's self when plugged into your car.
2) It makes it a lot easier to unlock the phone when it's lying down on your desk or table
Counter point: Same as above, set your phone to not be locked in a familiar space either via Wifi home or similar.
3) As another commenter pointed out, I use finger print unlock for MFA more than anything else at this point and having it on the front screen vs. the back is very handy.
4) Though there's no doubt I get my finger print scan 'wrong' more often than I did on the front vs when it was on the back.
I don't mind it one way or another but I thought my feelings about a finger unlock under the screen to be more divisive but it hasn't been as shit as I thought it would. I.e., I still find the lack of a headphone jack to be a much stronger pain point.
Our work is going a bit crazy with MFA timeout now and I'm really happy with my in-screen fingerprint reader.
No problems with it on the OnePlus 8 by the way, it's accurate and fast.
so, they make changes. all the time. for no reason. because they want more money, and a certain percentage of people are going to be drawn in by any given feature, even if it's a crappy alternative to an existing feature.
this isn't rocket science.
