DJI have been providing Android versions of their apps since at least the days of the Phantom 2 series, well before they had controllers with integrated screens.
I've been flying since then, always with Android devices.
This video is illuminating for those unfamiliar with how Auto Exposure works. He missed - or it wasn't possible when he did the video - the fact that on some controllers you can set a button for AE Lock which allows you to turn it on and off...
I am almost always using manual mode. I get a good exposure after I pop up the drone to my liking and then fly. I think you are asking for trouble if you use auto color balance though when you get into post production.
