A:Answer I just purchased this projector and it is great. At first I couldnt figure out the miracast, but I read that Android and iPhone stopped supporting that function. The way around this is to just hook a cheap chromecast up to the projector. Just get the cheapest chromecast because this projector is only HD -- it does not support 4k.
In addition to chromecast, you could easily hook any other HDMI source up like a Roku stick, gaming system, or laptop. I believe the new roku sticks have screen mirroring, so that may be a good compromise as well.
The projector does have a USB port that will act as a power supply to your roku stick/chromecast.
