Samsung Galaxy Watch has 5 powerful features that are turned off by default. Mute notifications on phone automatically silences your phone while wearing the watch and unmutes it when you take it off — found in Galaxy Wearable app → Watch Settings → Notifications. Universal Gestures lets you control the entire watch without touching the screen — Settings → Accessibility → Interaction and dexterity. Continuous heart rate tracking replaces the default 10-minute intervals with non-stop monitoring — Settings → Health → Heart rate. Fall detection triggers emergency alerts and SOS messages after a hard fall — Settings → Safety and emergency. Finally, Samsung phone users can automatically change watch faces based on daily Modes through the Modes and Routines app.
