I know that this topic has been beat to death but just thought I’d share. I fly in a VERY urban environment most of the time so I am limited on height and distance since I try to maintain line of sight. I flew yesterday using WiFi and my feed became very choppy. I decided to try my new OTG cable with my iPhone XS. I went further than the WiFi flight and the feed was still very smooth. I am running the current firmware and latest GO 4 app. When I took the Spark to my buddies house which is more out in the open the WiFi worked ALMOST as good as the cable, but I could still notice a difference. Also, FWIW, I just turned off Bluetooth and WiFi, I didn’t go into airplane mode. My map worked just fine and I was able to go further.
