I have the same problem on Samsung Galaxy S9+. Screen goes black when rotated to landscape, stays black until force quit.

Same here on Pixel 2 XL (Oreo 8.1.0). On mine, I can just switch to a different app and switch back to restore the screen. RetroArch 1.7.3 (Google Play Store)

I fixed this issue by a setting on my galaxy s8. When I would rotate my screen within retroarch it would go black, but if I swiped on the screen around where the soft buttons are I found a button that looks like joystick buttons, called "game mode". Likely a Samsung tool. Once I toggled full-screen it worked after restarting my game.

Seems to work fine for me on Pixel 2 upgraded to Android Pie

Th3dll's comment worked for me, after putting in full screen mode in the game settings, it worked, i have a galaxy S8+.

Thanks @th3dll that worked for me too i have the galaxy note 8
Edit: The Overlay and Icons are stretched then, I changed back to no fullscreen

the newest nightly fixed for me this bug @p-sam @beerenauslese @sub-atomic @BetaLeaf @th3dll @ctweeks2002 you all should test if this is fixed now

It would be great if Samsung would just stop putting weird "Game Optimizers" in their Android versions.
The solution @th3dll provided fixed it for me too. Thank you.
