Samsung, though not part of the initial list of partners associated with Android Wear, surprised everyone by announcing the Gear Live yesterday, which has already gone on sale in the US today, and is no on pre-order in India, for a price of Rs. 15, 900. Following the design philosophy of its other Gear devices, this Android Wear based Smartwatch will be sold along with the LG G watch. Both the Korean giants have their own first Android Wear based Smartwatches out, but lets focus on the Gear live here, which adds the unique functionality to measure heart rate using the hear rate sensor on its back. It looks and feels pretty similar to the other Gear watches, unsurprisingly, so lets take a photo walkthrough of this device, straight from the I/O developer event in San Francisco.
