I live in China now and I got Mavic 4 Pro. Overall, I love this drone but one thing that annoys me the most is its weak signal compared to my old Air 3S. My previous drone A3S had no signal issues at all, however, M4P has some problems and the signal is significantly weaker. Even when I use 4G connection it is the same, signal drops in places that A3S had no problem before. I talked to a few friends and they also have similar feelings that the signal is not as good as in their other drones.

Is it a common issue? Some people told me I may need to wait for a software update because M4P was too rushed and they messed up a few things. Or perhaps I should request a new drone from DJI?
 
Maybe it is because the dongle is now on the bottom. Or other interference on the drone.
But do you have FCC in China???
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
 
With the 4g dongle, in theory, the drone can fly unlimited based on how strong the 4g signal is
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.

At least you have a 1 year manufacturer's warranty to sort things out. LOL!
Not so for us U.S. gray market purchasers!
