[Android Central Question]

Is it possible to connect two Galaxy Note 8s to share what you are looking at immediately or at the same time? Similar to screen linking?

To have one see what's on the screen of the other? Simple. A VNC server on the one you want to see, a VNC client (sometimes called a VNC viewer) on the one you want to look at it with. Connected via a wifi router (or the internet, if the router the server is connected to has port 5900 forwarded to the phone).
