My phone has a display ratio of 19.5:9 (FHD+) and the scaling behavior of either or both of this program and Android sets the game to full screen width.

This causes playability issues, especially in the menu drawers, where functional items are displayed out of the screen space at the top and bottom of the screen and cannot be seen or interacted with.

Well hey, I enabled dev options on my phone which seems to have enabled access to more settings within the game. Setting it to widowed mode seems to fix the problem.
