Samsung has unveiled its latest challenger to the iPhone, the Galaxy S III, in London, saying the item won't reach U.S. consumers until the summer, according to UPI. The phone runs on Google Inc.'s Android software and comes with a faster chip, a quad-core processor developed by Samsung to allow users to watch video and send and receive test messages at the same time, The Wall Street Journal reported. It isn't known which U.S. carriers will offer the phone when it arrives, but the previous Galaxy model was available through all four carriers -- AT&T, Verizon, Sprint and T-Mobile. The Galaxy S II features a 4.8-inch screen, larger than both the iPhone's 3.5-inch screen and the previous Galaxy S's 4.3-inch screen. Analysts said the phone is a significant release for Samsung, though it may not topple the iPhone from its market position. "The S III is an evolution but not a revolution," Neil Mawston of Strategy Analytics said. "It's an improvement but it's not a game changer nor an iPhone killer. "Samsung's strategy is to offer good hardware at a cheaper price so it'll give Apple some pause for thought," he said. "It could put some pressure on Apple to develop a vastly improved iPhone 5."
