Phantom 3 pro
Dji go android 2.0.2
Firmware 1.3.2
Updated all firmware to bird, rc and batteries.  No more upgrade required showing in dji go status screen.
Did some tests inback yard, all was good.
Get to my shooting location and nothing but a blank white screen where the video feed should be.
Tried two different android devices.  Turned everything on and off a hundred times.

Bird will fly ok, all status looks fine.  Recorded video and pictures pure white, no static.  Video transmission status good.

Any   suggestions ?

Got home, it started working again.
Now, realized i had put in a new memory card before i left.
Getting home i put the latest firmware on the new card,  which was already shown as installed installed as shown by dji go and the text file on the old card.
It beeped for only about 3 minutes.
New text file on new card shows no update done.
But it works now.
Very frustrating.
