   Samsung might changed too much of their systems this time. I don't own Samsung phones as they're too expensive for me and the only reason I'm buying it might be fixing issues for this specific brand, so I can't help much here.

   I made an unofficial test build for the Samsung/OneUI external display problem:

   https://github.com/Kyuugit/moonlight-android/releases/tag/samsung-external-display-test-1

   This is meant for the issue where Artemis crashes or refuses to start streaming when “Fully External Display Mode” is enabled after a Samsung update.

   It also includes AI-found fixes for:

   • mouse/keyboard handling in the external display path
   • a hotplugging issue where you sometimes had to force close Artemis before it would detect/use the external display correctly

   There are two APKs:

   • artemis-external-display-standard-arm64-v8a.apk

     • Try this one first.
     • It is more likely to install normally.
     • Bluetooth keyboards should mostly work, but some special shortcut keys may not.

   • artemis-external-display-keyboard-adb-arm64-v8a.apk

     • Try this only if you need better Bluetooth/physical keyboard shortcut support.
     • This version includes the keyboard accessibility feature, which seems to make Play Protect/Samsung block normal installs.
     • You may need to install it with ADB.

   Important notes:

   • This is not an official Artemis build.
   • It installs as a separate app, so your existing Artemis/Moonlight settings and pairings will not carry over.
   • It was tested by me, but the implementation was fully built by AI.
   • I am not maintaining this as a proper fork. It is just a personal-use test build that I may update while I still need it.

   I am also encountering this issue with a pixel 8a on grapheneos stable + xreal glasses

   I consider this feature extremely important so fingers crossed it can be resolved
