2. Samsung Galaxy S III
The biggest rival to the iPhone this year was the Galaxy S III, the newest version of Samsung's flagship Android-based smartphone.
The Galaxy S III is the most sophisticated Galaxy phone in Samsung's line-up, running the company's latest quad-core Exynos process, Android 4.0 "Jelly Bean," and measuring just 0.3 inches thick. It also has 4.8-inch display, which means more screen real estate than earlier Galaxy S models.
Samsung armed the Galaxy S III with a number of new features, including "S Voice" for voice activation and commands, and "S Beam," which lets users share photos and other files via near-field communication.
