The Samsung Galaxy S II (also unofficially known as the Samsung Galaxy S2) is a touchscreen-enabled, slate-format Android smartphone designed, developed, and marketed by Samsung Electronics, as the second smartphone of the Samsung Galaxy S series. It has additional software features, expanded hardware, and a redesigned physique compared to its predecessor, the Samsung Galaxy S. The S II was launched with Android 2.3.4 "Gingerbread", with updates to Android 4.1.2 "Jelly Bean".

Samsung unveiled the S II on 13 February 2011 at the Mobile World Congress (MWC) in Barcelona.^[6] It 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.^[7] The Galaxy S II has a 1.2 GHz dual-core "Exynos" system on a chip (SoC) processor,^[8] 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 1080p full high definition video recording. It is one of the first devices to offer a Mobile High-definition Link (MHL),^[9] 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 is supported.^[10]^[11]

The user-replaceable battery gives up to ten hours of heavy usage, or two days of lighter usage.^[12] According to Samsung, the Galaxy S II is capable of providing 9 hours of talk time on 3G and 18.3 hours on 2G.^[12]^[13]

The Galaxy S II was popular and a huge success both critically and commercially,^[14]^[15] selling 3 million units within its first 55 days on the market.^[16] It was succeeded by the Samsung Galaxy S III in May 2012.^[17]
