Along with Google apps and services, we also get a look at some of the key health-tracking features of the upcoming smartwatches — including heart-rate monitoring, body fat composition, workout tracking, sleep tracking, and more. Unsurprisingly, the watches will have the Samsung Health and Bixby apps as well.

The Galaxy Watch 4 and Watch 4 Classic models are rumored to come with circular AMOLED screens and Samsung's in-house developed Exynos W920 chipset. They are also tipped to feature blood pressure monitoring, ECG, an SpO2 sensor to track blood oxygen saturation, and an IP68 rating for dust and water resistance. While the Galaxy Watch 4 is expected to be the spiritual successor to the Galaxy Watch Active 2, the Classic model will be a follow-up to the Galaxy Watch 3 — which is currently Samsung's best Android smartwatch.

Samsung is set to announce the Galaxy Watch 4 series at its Unpacked event on August 11. The company's next-gen foldables and the Galaxy S21 FE will also be unveiled at the same event.
