I posted this problem weeks ago in another thread and several people said they have/had the same problem. I can be in flight and everything is ok and then the screen will freeze and then it will go to the desktop. Then I will have to start the app all over again while the quad is up in the air. VERY ANNOYING! I haven't heard anyone complaining lately so I'm hoping that there is a fix that maybe I never heard about. Anybody know the fix? Thanks.
