So i manually calibrated the 6X using GPS. Did a force reset (hold 30sec power while connected to power source, then release and press again to start).
Apparently the 6X does not need phone GPS to function/calibrate, even in autocalibration mode.
Watch fixes on a plausible altitude (checked with google earth drop pin), everything good for one day.
Next day (even with altitude value ok) i get weirdness 2 floors climbed when i never did.
Then all of sudden i am 70m higher apparently than before, even though i am sitting in the exact spot (outdoors) i used to calibrate the previous day.
Been spending a whole week re-calibrating, experiencing weird drifts and floors appearing out of nowhere.
With the help of support i entered engineering mode and checked sensor data and they said it's fine.
Tried DEM calibration as well at some point, even calibrated it once with GPS and then turned OFF autocalibration when not in workout, etc..
What's going on?!
