Which smartphone launched Samsung's original Galaxy S line in 2010? It was the Samsung Galaxy S. Samsung announced the first-generation model in March 2010 and released it on June 4, establishing the flagship Galaxy S family that would continue through later generations.

The original Galaxy S ran Android 2.1 Eclair and used Samsung's own Hummingbird system-on-chip in many markets. Its 4-inch Super AMOLED display was a major selling point, offering strong contrast and vivid colors at a time when large, high-quality smartphone screens were becoming central to phone design.

The name can cause confusion because Samsung released several related Galaxy phones around the same period. The Galaxy Spica preceded the Galaxy S, while the Galaxy Ace was a separate, lower-positioned model. The Galaxy Note arrived later, in 2011, and began a different large-screen product line.

Regional versions varied in processors, storage, wireless bands, and branding, but they belonged to the same first-generation Galaxy S launch. The phone's success helped turn “Galaxy S” into one of Android's best-known flagship names.
