I'm trying to get setup with a process for backing up my photos/videos during my trip and I'm running into some issues. This is what I'm trying to do:

• Using OTG adaptor, copy files from DJI SD card to Phone SD card
• In DJI Go4 app, under editor and album, I'm using the "import" (upper left corner) icon to try to import the photos and videos
• Neither "Local Photos" nor "Local Videos" show the media on the phone SD card.
  

What am I doing wrong?

Thanks

Doesn't looks like I can edit my post. Here's another finding:

I tried to connect the remote and connect to the drone (SD card in the drone) and I tried to import using "SD Card" instead of "Local Photos" or "Local Videos" and it seems like I can't transfer 4k video via wireless. How am I supposed to copy the files to my phone?

Will you have access to a computer on your trip?

Are you inserting the SD card into your phone so you can upload the video to the cloud?

I will not have access to any PC since I'm doing a road trip in Switzerland and Italy. I'm essentially trying to make sure I can upload videos for my family but the cache on the phone is not large enough to show the full content of what would be on the drone SD card.
