The first software update for Samsung's new Galaxy Watch 3 is now available.
It adds support for blood oxygen monitoring, sleep ratings, VO2max, and more.
Blood oxygen analytics will only be available in select markets.
The Galaxy Watch 3, which was unveiled at Samsung's Unpacked event earlier this week, has already started receiving its first software update. Unlike the first update for the Galaxy Note 20 series, which doesn't add any new features, the Galaxy Watch 3 update brings a bunch of features, including support for blood oxygen monitoring.
After you install the update on your Galaxy Watch 3, you will be able to measure the amount of oxygen in your blood. However, the feature will not be available in Algeria, Angola, Canada, France, Iran, Japan, Libya, South Africa, and Thailand.
Apart from blood oxygen monitoring, the update also enables support for VO2max, which measures your maximum oxygen uptake during a workout. The update brings Advanced Running Analysis and Sleep Scores as well. While Advanced Running Analysis provides insights that can help users improve their running form, Sleep scores are aimed at helping users better understand their sleep patterns.
