Many have doubt Samsung's operating system Tizen and its first Tizen-powered smartphone, the Z1, but according to sale figures it did quite well. Samsung has sold over 1 million Z1 units and plans to launch several more Tizen smartphones to gain more market share.

They will come at varying prices, but don't expect a high-end Tizen smartphone. Samsung is probably concentrated on entry- and mid-range markets, and Tizen operating system isn't mature enough for a high-end device. There is also no word on when the new Tizen devices will arrive.
