Which Samsung smartphone line debuted with the Galaxy S in 2010? The Galaxy S line. Samsung announced the original Galaxy S in March 2010 and released it in June of that year, establishing a flagship smartphone family that continues today.

The first model, commonly identified by its international model number GT-I9000, used Android 2.1 and Samsung’s TouchWiz interface. Its headline features included a 4-inch Super AMOLED display, a 1 GHz processor, a 5-megapixel rear camera and expandable storage. The combination helped Samsung compete more directly in the rapidly growing premium Android market.

The name can cause confusion because Galaxy is Samsung’s larger device family, while Galaxy S identifies its high-end phone series. Galaxy A later became associated with mid-range models, Galaxy Note with stylus-focused phones, and Galaxy Z with foldables. Those are related product lines, not the line launched by the original Galaxy S.

Samsung followed the first phone with the Galaxy S II in 2011 and successive generations thereafter. Regional versions also differed: U.S. carrier models received names such as Captivate, Fascinate, Vibrant and Epic 4G, even though they belonged to the same first-generation Galaxy S family.
