I have a Razr flip phone that I often use folded halfway (laptop style) and watch videos on the top half while I do other things.

Certain video apps center the content across both halves of the screen and I have to activate split screen and put a random app on the bottom half of the screen.

Long story short, is there a way to split screen only 1 app to only the top half of the screen? I’ve tried to search for something but I’m coming up empty.
