I`ve got a problem after the last firmaware upgrade for P3pro.
I usually calibrate the compass before every new flight, and usually, I do not take off if I have got less than 15 satellites.
After the upgrade, in every place I choose for flying, I get first 19-20 satellites, but when I move the aircraft with my hand, suddenly, the satellites get down to 2-3!!!.
The same it happens when the aircraft flies: from 19-20 satellite to 1-2- or 3 satellites and then goes automatically to Return To Home!!!!.
I would just mention that, the places where I am trying to fly are the same places where, before the upgrades, I flew without any problems!!.
Pls heeeelp!!!!

That's a mystery.
I'm wondering why you move the Phantom from the place you set it  after it has acquired satellites?

If you are doing it to calibrate the compass, try not doing that.
You don't need to recalibrate every flight and calibrating unnecessarily introduces the potential for getting a bad calibration.

i believe it mostly depends on your environment and signal quality can vary from spot to spot
