When I'm trying to rotate Mavic (using left joystick), I very often have ATTI mode:

[["2019-09-22 17:01:03","Warnings","Camera Sensor Error"]],[["2019-09-22 17:01:04","","Compass Interference. Temp Max Altitude: 5m"]],[["2019-09-22 17:01:16","","Satellite Positioning Off. Fly with caution"],["2019-09-22 17:01:22","","Weak GPS signal. Positional accuracy may be compromised. Please fly with caution."],["2019-09-22 17:01:22","","Temp Max Altitude Approached.

At the same time I see that there is no GPS signal, in few seconds it becomes 2 (out of 5).

After that I again see 5 out of 5 and 20 satellites.

Is that GPS problem or compass issue?

Something is not right.
You have just about every error the Mavic can throw at you.
Has this Mavic been/had/have and issue before? Has this Mavic been opened up? Submerged in water?

It has small crash and yes, it has been opened.

Usually issue happens when I'm rotating Mavic.

If you have conflict between compass gps or IMU , your system will drop gps in favor of compass, your craft cannot fly without compass but it can without gps, my feeling is you encountered problems on the ground which exacerbated in the air culminating in all of these problems.

Please, ignore camera issue - I resolved it.

So, do I need to replace compass or GPS module?

I have this issue almost every time I'm trying to rotate my Mavic in sport mode.

Does it only happen in sports mode?

Both in sport and normal mode.
Usually during sharp turn.
