I have been using a Samsung Note 2, and today I got out the gear and upgraded everything. The app as well. The Note is upgraded to android 4.4.2, which should be well beyond what the app needs, 4.1. Before I updated, I got nice FPV fotage all the time, but now it's just a black field. I tried with my S5, and that worked without a hitch, so it's not an error in the drone or remote. But I prefer to have my remote and phone separate, and the Note has a bigger screen. Even uninstalling the app and reinstalling it didn't help at all. Filming and photographing works just as well as with the S5, but not FPV. Any idea what this may be?
