I have a raspberry pi: it is normally run 'headless' (sans monitor). I would like to be able to connect the video output on a Samsung Galaxy Phone. For this exercise, the solution must use a wired connection (HDMI, USB) and not rely on a network connection (SSH / VNC or similar).
My Google search brings up articles of how to cast video from the Android device through HDMI. I would like to wire and direct HDMI into the Android device's display.
Assuming there is a cable that can bridge HDMI into the Android device: does Android support wired HDMI capability? What is the nomenclature for the capability?
Bonus: can the same thing be done from the raspberry pi's USB port? That is, direct the video out through a USB port, through a USB cable and into the Android device for display?
