I was having an issue with my hs720 connecting to my Samsung A5. It would show up in my connections, however when I tried to connect to it...it connected but said internet not available. I tried everything and realized when I started the flight app, that everything was working and I actually was connected all along. The internet not available message is what threw me off...I was still connected to the drone with camera working on my phone, even though it said internet not available.
