I can’t video or take pictures because the app thinks it needs a SD card. But my controller is plugged into my phone I thought it would just go right to the phone. DJI Fly works without a SD card.
Full resolution videos and photos are always written to the SD-card in the drone.
You can cache Low resolution videos and photos to your smart device (iPhone) by enabling it in the Camera Settings.
When there’s NO SD-card in the drone, caching videos and photos does NOT work.
