That is simply a reflection of the number of different Android devices available.Mate, have a look at the reviews on the dji go app for androids, hundreds of complaints about compatibility issues.
The simple truth is that the app is demanding and requires a fast processor and enough RAM to run properly.
If you have a substandard device (whether Apple or Android), you will be disappointed.
The app works equally well on a good tablet of either flavour.
Don't get confused by marketing spin.on the side of the box the mavic comes in, it says, made for iphones
That doesn't mean it's made especially or exclusively for iphones.
It just means that it works on iphones
The real situation is that you are more likely to have problems using a substandard tablet whether it's Android or Apple.I'm not saying it wont work, its just more likely to have problems using android.
There are Android devices that run the app at least as well as any Apple device.
