Have had this watch but constantly gives me wrong reading on the spO2 reading.
9/10 times I get readings that would suggest I would be in critical condition. 80/86% or just won't give me a reading for a couple of attempts.
The watch is fitted correctly and close to the skin, the sensor is clean and no scratches in the back.
How likely would it be that it has had a faulty spO2 sensor from factory? It's been like this on and off since I got it less than a year ago.
Heart rate seems accurate enough compared to manual recording of my pulse.
I know it's not 100% accurate but I would expect a plausible reading. Nothing far-fetched suggesting hypoxia.
