This is probably a wildly niche situation, but I learned about OSU!droid and was interested in trying it with my galaxy tab s6 lite, figuring the s pen would be a pretty perfect way to play.

The only problem is that the main way to hit bursts and streams is to aim at the objects with one hand and tap the side of the screen with your offhand, but the s pen disables touch input while close to the screen.

I did try just connecting my keyboard with a dongle and setting up a key map, but the game doesn’t let you launch with it enabled for competitive reasons.
