I'm from Brazil and I have the Creator combo. We're already using the CE standard here, but even so, compared to the Air3s signal, the M4 signal is much lower. I believe that in an update they will adjust these things. The signal loss is...
At the end after inspecting my drone, DJI decided to replace it, and I just got a brand new Mavic 4 Pro. So it seems it was a real problem.
This weekend I will test my new drone and let's hope the signal will be much better.
Last week I decided to return my drone to DJI and this week they will let me know if drone has a problem or if it is something else. Below the photo of poor reception. I even tested it against my old mini 3 pro and my small drone did much better...
You are right, but this theory doesn't work in my case :D So now I wonder if this is a general issue and wait for update or is it a hardware problem related to my drone or RC.
Yes China has FCC so the signal is much better than in some other regions.
For example, my A3S can easily fly up to 2 km while M4P struggles to reach 700 meters
