Samsung has today lifted the covers off the Samsung Z, the world's first commercially available smartphone powered by the Tizen operating system. Those who keep a keen eye on the consumer electronics industry will be familiar with Tizen through its integration with Samsung's smart cameras and intelligent wrist wear, such as the Samsung Gear 2 lineup of smartwatches. However, the latest "premium" smartphone from the Korean outfit is the first device of its type to be launched with Tizen on-board and will get its first public outing during tomorrow's Tizen Developer Conference in the heart of San Francisco.
