Samsungs first generation of smartwatches is officially ditching Android. SamMobile reports that the original Galaxy Gear is being upgraded to Tizen, the operating system used on the newer Gear 2 and Gear 2 Neo (but not the Gear Fit, yet another model released this spring.) Samsung has made a point of differentiating its software from stock Android — its various Android smartphones are loaded with design tweaks — but in this case, the main difference will be in added features; According to SamMobile, the update brings most of the Gear 2s new capabilities over to the Galaxy Gear. Most notably, that means the old Android step-counter now tracks sleep patterns and more detailed exercise measurements, a standalone music player can store music to be synced with Bluetooth headphones, and battery life should be noticeably better.
