While flying the app goes black screen then goes to DJ GO 4 start up screen then comes on agian, I am using LG stylo 2 V and this phone is strickly for my Mavic. Lots of space. Dont think its ever done it while recording.

Hi Wilddeer, since LG stylo 2 V is not in our device recommended list which might be incompatible with DJI GO 4 app.
Besides, please try to use another original USB cable to connect your phone to controller and please ensure that you do not have any programs running in the background.
