Fimi X8 v2 VS sg906 SE in gps and calibration!

Very disappointed that a 4 times cheaper drone don't lose satellites when I take it to calibrate the compass!
unfortunately the Fimi X8 SE v2 2022 loses satellites immediately when I take it to calibrate and since it's already a weak drone discovering satélites ( only as gps e glonass) but losing 3-4 satellites when trying to calibrate ( and we have to take it our hands to calibrate with one meter height) makes it very unreliable to the place you can use it !
without a good compass and gps system ,for me forget it!!! I will never trust this drone !
I doubt that a firmware update will improve this type off thing but well maybe? or can make it worse ! that's the main objective off so many updates in smartphones and other electronics ( and they don't let you roll the update back for that reason) it's called planed obselecence!!!
