I have found an OTG cable laying around so I decided to try it out. Plugged it into my Nexus 6P and immediately asked about which app I'd like to use to perform this action. After selecting the GO 4 app, my phone started charging off the Sparks remote controller. I have tried connecting to the remote, and it did enable the live stream feature but it kept saying aircraft disconnected, and I wouldn't be able to fly BUT I was able to see all the options on the screen, just like you see when you fly it (that's how I saw that the live stream was enabled and there). Once I switched the connection to the Spark in my wifi settings, I gained access to the drone but live stream wasn't there at all. On the other hand, if I connect the Spark to an iPhone, live stream works immediately. Not quite sure what's going on and I don't seem to find any tutorials about this topic. In addition, just so I can make sure that it isn't my Nexus 6P that is messing up, I have also tried the same things with a Pixel. When I plugged in the remote controller with the OTG cable to the Pixel, the Pixel didn't even ask about how to perform the action.
