Hands only not working on Unity

On Unity 6, with the V85 of Meta SDK, I choose in "Hand Tracking Support" the "Hands only" mode so controllers aren't supposed to be available in build.

However, controllers are still available in my app so I tried to use the "Controller Only" mode so it disable correctly the hand tracking in my app and it shows up a window to use controllers when I try to lauch my app.

Why it's not making the same for hand tracking mode ?

What you’re seeing is likely because “Hands Only” in the Meta SDK mainly declares hand tracking as the required input capability for the app, but it does not always hard-block controller presence at runtime the way “Controllers Only” hard-blocks hands. Meta’s own Unity docs say Hands Only sets the Android manifest hand-tracking feature to  required="true" , while Controllers and Hands sets it to  required="false" ; that explains store/runtime capability requirements, but it does not explicitly say controllers will be forcibly disabled in-app whenever they are detected. 

Meta’s documentation describes Hands Only as “use hands as the input modality without any controllers,”

If you want true hands-only:

  • Manually ignore controller input in your app
  • Or detect controllers and hide/disable their interactors
