They tell you up front though, as far as I know they’ve never sold a health sensor into a country and then disabled it later, which is what it sounds like parent comment is describing
I have a Samsung Galaxy S8+ I used the SPO2 sensor all the time. Then I think it was last year (2019) when it was removed without warning. But like I said Samsung probably buried that info in 5000 lines of an update notification.
I can understand new devices being sold would not have the device enabled due to some patent or legal issue. But to have Samsung disable a physical device on a two year old phone is frustrating. I bought the phone I own it Samsung shouldn't allowed to do such a thing or at least make it more obvious and give the option to opt out of the change.
