Pulse oximeter is totally broken with 4.70 on Vivoactive 4. Medical pulse oximeter shows me 96-100, Garmin 85-88, sometimes below 80. I am confused and angry. Measurement was correct on earlier version of firmware.
Me too - alternative medical SPO2 has me at between 5-10% higher most of the time - one of the main reasons for choosing VA4 so I hope this can be fixed. Be aware def big difference if wear as advised firstly above the wrist. Only just bought the watch so never tried the 4.6
