Earlier, Samsung released the first watch galaxy 4 series to run the Wear OS 3 jointly developed by Samsung and Google, and Google released an update for the Galaxy Watch 4 that will add some practical features.

Google released an update for the Galaxy Watch 4, which will add fall detection and practical functions, let's take a look at what features are available.
✅ 1. Fall detection function
Not only can the user be detected when exercising, but also when the sensitivity is manually adjusted, it can also be detected when standing. Even if the Galaxy Watch 4 isn't paired with the phone, the fall detection feature works.
✅ 2. Tap gestures
Users can use simple gestures to launch built-in features or apps more quickly.
✅ 3. New surface
Is the surface too monotonous now? After the update, users can choose 4 kinds of surfaces according to their preferences, and each of the 4 surfaces has different designs and characteristics.
At present, the Galaxy Watch 4 update first provides user updates from the United States and South Korea, and I believe that other countries will have to wait for a while.
