When I got my obsidian over a year ago, Note 4 runs DJI GO4 with unsatisfactory results. Main problem was pixalated video feedback and lag. When I got my Mavic 2 a few weeks back, I tried the Note 4 so I can fly mavic and phantom at same time and needed extra screen. I was surprised when it worked on the Mavic 2. So I tried it on the phantom and also worked. I mainly use an ipad pro 10.5 for both.
