Hi I am finding that for some time I am forced to calibrate the oximeter every time I turn on the clock.
For the outdoor activity it is ok because it searches for the gps and finds the correct altitude while as soon as you access it you must have incorrect values.
I tried to calibrate both altimeter and barometer even manually but nothing.
Example:
I live at 300mt the watch gives me 1600mt
just turned on, after automatic gps adjustment it works for me.
I turn it on at 230mt the watch gives me 1400mt.
Version 14.10 but also from previous versions.
