Back-forth swipe over home button?
I just got an iPhone SE 2020. I have noticed that when I swipe over the home button right-left-right, left-right-left, top-bottom-top, etc the whole screen drops exposing an empty area with an “up” chevron at the bottom. I can’t find any documentation that addresses what this is doing or is for. Any info would be appreciated. See screen capture below:
