I know it's not officially supported but OTG connection has transformed my Spark experience. Got the Fly More Combo, and my first couple of flights were a complete mess with horrendous video lag and frequent disconnects (I use a Sony Xperia Z for it but was same with my Samsung Galaxy S7 Edge). Tried the OTG solution and it has been night and day for me. Burned through 2 Batteries and recharged and did the same and NOT A SINGLE DISCONNECT AND ZERO VIDEO LAG. Seems to me DJI should support this as it solved the only issue for me.....
