FYI- If you look very closely at the video tile on the bottom left you will see XR inside XR. You can't get that capability anywhere else.

We really are emulating an XR headset inside the Galaxy XR. That hasn't been done before- with a real OS that boots and a stereo passthrough renderer. Can't explain it clearer than that.
Here's another video that shows it. Look closely at the lenses of the virtual XR headset.
The beauty of booting a full OS means we really can make software that works as though its on a real device
