Marketing videos of theSamsung Galaxy Watch 4andGalaxy Watch 4 Classichave leaked courtesy ofSamMobile. The videos show the new UI design and features of the two smartwatches. Samsung is expected to unpack the Galaxy Watch 4 series with therevamped Wear OSon August 11and the new videos give us a fair idea of the visual changes coming to the wearables.
First up, the leaked videos show that both the Galaxy Watch 4 models are runningWear OS 3and pack the Google Play Store. This was a given because of the company’s partnership with Google for its newOne UI Watchuser interface and the core Wear OS 3 experience. We also see icons for other Google apps on the smartwatches, including the Google Maps app for navigation.
The videos tease a bunch of health tracking features headed to the Samsung Galaxy Watch 4. These include heart-rate monitoring, workout tracking, sleep tracking, body fat composition, and more. The last one on that list is a new feature. It was previouslytippedthat Samsung would include a Bioelectrical Impedance Analysis (BIA) sensor, commonly found on smart scales, to measure the human body’s percentage of fat to muscle and other tissue. Looks like the rumor was accurate.
Besides the aforementioned features, the Galaxy Watch 4 and Watch 4 Classic are also expected to enable blood pressure monitoring, ECG measurement, SpO2 checks, and more.
Elsewhere, we see several new watch faces coming to the Galaxy Watch 4 models. To add to its retro appeal, the Galaxy Watch 4 Classic appears to have more mechanical watch faces compared to the standard Galaxy Watch 4. Meanwhile, the video also shows watch faces that include widgets for activity goals and other information. Some of these could definitely be customizable to display widgets of a user’s preference.
