I have a Phantom 3 Professional.  I take off and the screen freezes.  Then about 30 second later it goes black.  I can still fly the drone and receive positional data and speed from it and I can switch to map mode, but I do not get any video feed.  The video does record the flight for download after the flight.  Is this an update problem?

How long you've owned it? it performed fine before?
What mobile device you use for the aircraft?
Can you please make a screenshot and upload it here?
