You can do this! The XReal Airs will take a signal certainly from Samsung smartphones and a few others. I'm expecting wider compatibility from the One line but we'll see how that shakes out.

The fly in the ointment is battery life. Given only a single USB-C port on the phone and wanting to avoid having to find a hub with Display Port going one way and power the other, the glasses have to get powered from the phone itself.

Also worth pointing out that XReal themselves make a phonelike device for exactly this use case. No idea how good it is though.
