Hi all, I've found another thread about this issue but it was unresolved and from 2014. I have tried using the Phantom 4 to record video and so far it's only a 70% chance that the video will actually be saved. I've used the record button on the DJI Go app and I have used the RC record button. In both situations, I wait till the timer on the record button starts, and then I start flying away. Problem is, half the time the video doesn't get saved and I don't realize this until I look at the SD card at home. Do I need to wait a few minutes before I turn the drone off so that it can save these 5 minute, 4K clips? Other longer clips have been fine. I'm using a 64GB Sandisk Extreme Pro 95 MB/s UHS-1 card, though I've had the same issue happen on the included Lexar. So far I haven't discovered a pattern as to what triggers this false recording.
