why can I buy a cheap 35 dollar watch to track my bp o2 and heart rate but my galaxy watch can't? Is there an update you can implement or do I have to trash my $200 watch and buy a cheap one off amazon?
there are ways to activate it. but its not official outside Korea (blood pressure and ecg both work on my watch 3 in uk). the cheaper watches are not medical certified (unless stated) o2 is working on watch 3 as from last update.
