The Samsung Galaxy S II’s international model became available for purchase on May 1, 2011. It was an instant success and reached 3 million pre-orders worldwide. It became available in the United States on all four major carriers with the exeption of Verizon Wireless, which went with the Samsung Galaxy Nexus instead. On September 16, 2011 Sprint released the Samsung Galaxy S II, also known as the Epic 4G Touch. Then T-mobile launched their Samsung Galaxy S II on October 12, 2011. Next came AT&T which released two Samsung Galaxy S II models. The AT&T Samsung Galaxy S II was released on October 2, 2011. The AT&T Samsung Galaxy S II SkyRocket released on November 6th, 2011. Then U.S Cellular came late to the party with their Samsung Galaxy S II on March 1, 2012.
The International Samsung Galaxy S II features a dual core ARM Cortex A9 processor along with Samsung’s Exynos 4210 SoC. It has 1GB of RAM with 16GB of internal storage. The storage is expandable up to 64GB with the MicroSD card slot placed under the battery. The screen is a Super AMOLED Plus dispay with Gorilla Glass at about 4.27 in.
All Samsung Galaxy S II models feature an 8MP camera that takes good quality photos. Some might suggest that its compatable to the iPhone 4s camera. The Samsung Galaxy S II was one of the earliest adopters of the NFC (Near Field Communication). HDMI output is also a feature worth taking note of. You can purchase a MHL adapter and output content to a HD television. The device will come with Android 2.3 (Gingerbread), however it is upgradable to Android 4.0 (ICS) – depending on your model.
The four U.S varients of the Samsung Galaxy S II really complement each other with the exception of the shapes, proccessors, and supported radio frequencies. The original AT&T Samsung Galaxy S II is really similar to the international model.
Since the Samsung Galaxy S III is the new flagship device for Samsung and most of the U.S. carriers, the price of the Samsung Galaxy S II has dropped to $150 and as low as $99 with AT&T.
