Lots of people have given their opinion regarding fingerprint vs facial unlock. But for me, personally, the reason I would be loathe to give up the fingerprint sensor on my Pixel 3 is the fact that I can swipe up or down on it to pull down the notifications on the phone. Since I've got the 3XL, it's just a nice little usability thing that makes it slightly easier to use such a large phone with just one hand.

I'd miss it a lot, and it's one of the reasons I think I'll keep my 3XL for another year instead of upgrading to the Pixel 4.
