Hello there!
I'm a bit of a noob when it comes to drones, so it is very possible that I'm doing something wrong.

I bought a mini 3 pro recently and when I was setting it up at home, I noticed I was having some issues with GPS. I assumed this was because I was inside and decided to take it out for a fly.

Outside I kept having the same problems. Because I am a noob, and from a small town, I thought to myself that it could be an issue with the network not being strong enough in that area (?)

Fastforward to now, I came to Sweden, and decided to try to fly it again. Again, same issue. GPS errors and what not. Now I'm thinking this might be an issue with the drone itself which would be a pain.

I'll post the screenshot I took from the DJI app showing the errors. Maybe someone here will be able to give me some more tips on how to solve this. Anyway, thanks so much for your help guys! much appreciated

Hi,

Try to do a firmware update or refresh with DJI assistant.

If that doesn't work, sending it in for repair is safer.
