Samsung was one of the first to jump into the smartwatch scene with its custom Android-based Galaxy Gear. Back then, not many paid attention to what many labeled as a fad that would disappear in a few months. Now almost two years later, the smartwatch market remains and Samsung is unveiling yet another wearable innovation in the Gear S2 and its rotating bezel control. But before you go knocking this smartwatch because it isn't running Android Wear, perhaps you might want to take a second look. This time, Samsung is making it work with any modern Android smartphone.
