The latest software update for the Samsung Gear S3 smartwatch pushes the Tizen version up to 4.0.0.2, weighs around 300 MB, and comes with sleep stages info support for the Health widget, more indoor workouts and back-to-back workout for Samsung Health, improved Quick Panel UI, and more. Sadly, it is only available in the US for now.
