If you’re trying to run an app or game while using Samsung DeX and come across the error “game/app can’t run in DeX app designed for touch screens.”

All you need to do is turn on Developer mode inside of Samsung DeX.

Here’s how to do that:

  • Head to Android System Settings
  • Select “Samsung DeX” (should be at the top of Settings)
  • Click “About Samsung DeX”
  • Click where it says “Samsung DeX” 5 times to enable Developer Options.
  • Click “OK” in the popup.
  • Relaunch your app or game and it should without an error. ?
