Do you want to use your phone while wearing an AR/VR headset? So the screen is large enough to cover a whole wall in a room. The app lets you do this. You can watch videos, read articles, scroll shorts, and so on with low latency and high quality. Note: the app does not allow you to remotely control your phone. Hint: you can increase auto screen Auto-Lock timeout to prevent screen mirroring disconnects when your phone screen locks.
