Samsung Galaxy S2 D710 is a touchscreen-enabled, slate-format Android smartphone designed by Samsung Electronics. 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. The user-replaceable battery gives up to ten hours of heavy usage, or two days of lighter usage. It has additional software features, expanded hardware, and a redesigned physique compared to its predecessor, the Samsung Galaxy S.
