After announcing the Galaxy Watch 3 earlier this week, Samsung has already rolled out the first major update for the new smartwatch. The new update enables blood oxygen monitoring among other new features.

According to SamMobile, the OTA update, which is roughly 80MB in size and can be installed through the Galaxy Wearable app, is among the many updates promised to bring new health features to Samsung’s new smartwatch.

The arrival of blood oxygen monitoring follows the launch of ECG monitoring in South Korea, which also recently received approval from the U.S. FDA.

Unfortunately, blood oxygen monitoring isn’t available in every country you can buy the Galaxy Watch 3. The countries where it won't be available include Algeria, Angola, Canada, France, Iran, Japan, Libya, South Africa, and Thailand.

In addition to the arrival of blood oxygen monitoring, the update also includes advanced running analytics, sleep score, and VO2max; the latter feature will check the maximum amount of oxygen you utilize during exercise to improve your endurance.
