Samsung disabled the oxygen sensor (SPO2) on their phones for Canada. For other countries they moved access for the SPO2 feature further into the Samsung Health app. But for Canada SPO2 sensor access is gone not accessible.
No warning (probably buried in an email) just one day my SPO2 sensor stopped working. I suppose it was due to some legal thing but it certainly pissed me off. I'm never buying Samsung again why blow $1000 on a phone only to have physical hardware disabled?
