I found my original question to DJI. Here it is: The storage full message turned out to be because my 8gig internal memory was full so I fixed that. Then no more message.
I flew my
Mavic 3 Pro for the first time in over 4 months. I have to admit I didn't take proper care of it during this time. It was uncovered and got very dusty and dirty. I cleaned it off with a wet cloth. So I took it outside and it sent my phone a text to unlock the airport. I did a short test flight. The only problem was there was a message in a brown box saying storage full, even though in settings it showed over 200 gig of storage. But it recorded OK.
Now I have a new apartment about a mile from my house which has no wifi. When I tried to fly it said not logged in. Obviously I'm not always going to be flying places where there's no internet. Fortunately I had my phone that has internet, and I created a Hotspot which allowed me to fly.
My main problem was the video kept stopping. It just froze up in till I landed. When I landed, it would start working again. But it froze up about 5 times. As you know this is not acceptable.
I sprayed my SD card and it's socket with contact cleaner, but this didn't help. I think I had this problem before, and the solution was to switch to the built in memory and then back to the SD card. I will try that.
But the main two problems are the video freezing and needing internet to fly when it's saying I'm not logged in.
