After making its way into Samsung cameras and smartwatches, the Tizen operating system is finally on a phone. The Samsung Z is the first Tizen smartphone, representing a third pillar alongside Samsungs efforts with Googles Android and Microsofts Windows Phone. Samsung calls it a premium device, but the specifications are fairly pedestrian: a 4.8-inch 720p AMOLED display, a 2.3GHz quad-core processor, and an 8-megapixel camera. Samsung says the open-source OS delivers a fast, optimal performance with improved memory management along with a faster startup time and immediate multi-tasking capabilities. The company is also touting Tizens web rendering and scrolling performance.
