The Samsung Galaxy S (GT-I9000) is an Android smartphone that was announced by Samsung in March 2010. It features a 1 GHz "Hummingbird" processor along with 8–16 GB internal Flash memory, a 4-inch 480×800 pixel Super AMOLED (PenTile) capacitive touchscreen display, a 5-megapixel camera and on select models, a VGA front-facing camera. The base version of the phone, the GT-I9000, was quickly followed by variant models for the US carriers, including the Epic 4G, Vibrant, Captivate, and Fascinate.
The Samsung Galaxy S has a PowerVR graphics processor yielding 20 million triangles per second, making it the fastest graphics processing unit in any Android phone at the time of release. It was the first Android phone to be certified for DivX HD, and at 9.9 mm it was the thinnest Android phone at the time of release.
