Hi Ardi,
Thank you for this idea. Generally sharing the screen from mobile device will be easy. The real pain is taking control (with each Android update there are more and more restrictions, as people got scammed and robbed this way).
Also Android blocks capturing of mobile screen when there is DRM protected content visible on the screen as well as web browser in incognito mode etc.
We will try to add screen sharing from mobile in v2.x of the app (together with full Android TV support).
