The big factor in all of this is Androids most likable feature is also its biggest flaw, open source. Building the app for Apple is easy, one os, a couple different hardware setups and that's about it. Android has Pure Google which runs dji the best, but then you have Samsung who adds a hurdle with touchwiz and very slow updates, just to name one example. The other major problem on here is the guy that buys a drone then goes to Walmart and buys a $49 Android RCA tablet, spends a week bitching about how bad Android and dji are because it won't work. Finds a way to finally get the bird off the ground just to slam it into a tree. My S9 plus still isn't an approved device through dji. It still worked fairly well except for the occasional disconnect. This is alot more frequent while flying the spark.
