Samsung has officially launched the Samsung Galaxy S II, the 4.3-inch Super AMOLED Plus sequel to 2010’s best-selling Galaxy S. The WVGA smartphone runs a 1GHz dual-core processor with an 8-megapixel, Full HD video capable camera and NFC support, but still manages to be 8.49mm thick at its thinnest point.

There’s also NFC, WiFi a/b/g/n, Bluetooth 3.0+HS and HSPA+ support, while the OS is Android 2.4 Honeycomb. Pricing hasn’t been announced, but the Samsung Galaxy S II is expected to go on sale in Q2 2011, perhaps as early as April. We’ve also separately confirmed that Vodafone will be ranging the device. Standby for hands-on and video!
