After several days of flying, I've had no issues at all with the newest app and firmware (even the mysterious 1.4 for Android users with the A-model RC). From reading various posts here, it seems that they have fixed several previous issues. Those who had mobile-device issues still have some of them, but those seem to be device-dependent.
I like envisionabove's comment "... and truthfully they [all issues] will never be [fixed]." This is not military- or industrial-grade machinery. During the early days of PCs, every OS upgrade fixed one thing and broke three more. But we loved them and stuck with it!
Go flying. Take great pictures!!
