Samsung Galaxy S II
The Samsung Galaxy S II (GT-I9100) is a smartphone running under the Android operating system that was announced by Samsung on 13 February 2011 at the Mobile World Congress. It is the successor to the Samsung Galaxy S, with a different appearance and significantly improved hardware.[6] The phone is also the predecessor of the yet-to-be unveiled Samsung Galaxy S III. The Galaxy S II was one of the slimmest smartphones of the time, mostly 8.49 mm thick, except for two small bulges which take the maximum thickness of the phone to 9.91 mm. The Galaxy S II has a 1.2 GHz dual-core "Exynos" system on a chip (SoC) processor, 1 GB of RAM, a 10.8 cm (4.3 in) WVGA Super AMOLED Plus screen display and an 8 megapixel camera with flash and full 1080p high definition video recording. It is one of the first devices to offer a Mobile High-definition Link (MHL), which allows up to 1080p uncompressed video output to an MHL enabled TV or to an MHL to HDMI adapter, while charging the device at the same time. USB On-The-Go (USB OTG) is supported. Samsung Galaxy S II Android 4.0 (Ice Cream Sandwich) supported.
