Samsung's First Tizen Phone !

Samsung Electronics Co. said Monday it will begin selling a smartphone using its Tizen operating system in the third quarter of this year, advancing the company's plans to reduce dependence on Google's Android software.

Samsung, the world's top smartphone maker by sales volume, said in a statement that the smartphone called Samsung Z will go on sale in Russia first. 

It said there are plans to sell the phone in other countries but didn't name them.

Unlike Apple Inc. with its own operating system, Samsung's popular Galaxy smartphones and tablets use Google's open source Android platform, a reliance that prevents Samsung from challenging the dominance of Apple's App Store and Google Play in the lucrative market for smartphone apps.

The Tizen phone will have preinstalled apps and users will have access to additional apps through Tizen Store.

Samsung has been encouraging the development of Tizen apps but the numbers available are likely to be small in comparison to the App Store and Google Play.

The South Korean company said the Tizen smartphone has a 4.8-inch high definition display, a fingerprint sensor for security and a "slim, angular" design.

It said the operating system will allow users to browse the Internet faster and utilize applications more effectively.

Superficially, users may not perceive much difference from the Android operating system because it and Tizen share Linux as the underlying framework.

The Samsung Z will be shown at a Tizen developer conference in San Francisco this week.
