- facilitate the infinite scroll

- remind you that the phone is in your pocket, to initiate the infinite scroll

I find reading ebooks and long texts like wikipedia a lot more enjoyable on my 6.8" AMOLED panel than on the smaller screens i've had before. You can also doomscroll on smaller screens.

Sorry but this is maximum level conspiratorial thinking. Meta probably has some created some incentive for OEMs to make larger screens by way of people liking content consumption but the idea that they’d be paying for that is ridiculous lol.
