Before DJI GO (Before Phantom 4) was updated and now works on Android Pie I bought +10 Euro Filmic Pro. Was it worth it? My answer is no & sometimes yes. When I was filming the coast glittered filmic pro but in the forest landscape in overcast weather, I think stock app on OnePlus 6 won and DJI came second.
In my test, all apps are set to auto. Have text on because I speak quite unclearly
