Samsung’s flagship smartphone for 2012 is now available in 28 countries around the world but unfortunately, the United States is not one of them. The Galaxy S III Android smartphone saw record demand ahead of its launch, and now the handset is available in more than two dozen markets globally. First announced at a press conference in London earlier this month, the Galaxy S III features an ultra-thin design that was inspired by nature. Spec highlights include a quad-core 1.4GHz Exynos processor, a 4.7-inch 720p HD display, an 8-megapixel camera, 1GB of RAM, 4G LTE connectivity, Android 4.0 Ice Cream Sandwich and a case that is just 8.6 millimeters thick. The international version of the Galaxy S III is currently available for preorder in the U.S., however carrier-branded versions not expected to launch until some time this summer.
