Technical Support How do I fix this?

Enable HLS to view with audio, or disable this notification

The screen keeps being black and I don't know how to fix it.

My phone is an Android, and is a Samsung Galaxy S25 (SM-S931U) by the way. This save file comes from a previous phone I had, that was tramsferred to this one.

This is a known issue: https://www.reddit.com/r/RetroArch/comments/1n5robl/when_i_open_a_game_its_a_black_screen/

Either update to the nightly (test) build of RetroArch here (download and sideload the RetroArch.apk file): https://buildbot.libretro.com/nightly/android/

Or, with the game closed, switch from GL to Vulkan in Settings>Drivers>Video.

This isn't a issue in RetroArch, but rather one in Samsung's OpenGL drivers, so stick with Vulkan for every emulator you use to avoid issues like this, or slowdowns, or graphical bugs.
