The first Android phone debuted in 2008 -- just a year after the iPhone's arrival -- but Google's mobile OS was a slow starter, chugging along with incremental improvements and sales. Early Android phones strove to mimic the iPhone's elegance, power and usability, but never quite pulled it off until Samsung's Galaxy S series came along. The Galaxy S III, released in spring 2012, was arguably the first Android handset to surpass the iPhone in some areas. Its 4.8-inch HD display made the iPhone 4S's 3.5-inch screen look puny and outdated; it had 4G LTE (the iPhone 4S didn't); and it had innovative (if somewhat gimmicky) features like S Beam for wireless file sharing. The S III continues to sell well, and has helped establish Samsung as Apple's top rival in the global smartphone market.
