The Samsung Galaxy Watch 3 has received many new features, including support for the company's SmartThings platform. The update, which is rolling out now, should also improve the smartwatch's reliability and stability.

Given time they will start to remove features - just like they did with the Galaxy 2 - which I bought and quickly found out - eg they removed the oxygen saturation measurement - something I bought the watch for as I have health issues. Noticed it made its way back on the Galaxy 3
Not so sure I trust them now - hardware is good but the company ethos - not so good
It has nothing to do with the Company Ethos, at least in the US, I believe it has to do with the FDA and what they will and will not allow them to put on the phone. That's why the ECG was disabled at the beginning!
