英语科学技术新闻：三星发布世界首款Tizen智能手机。

The Samsung Z will go on sale in Russia in the July-to-September quarter.

Most Samsung phones currently use the Android platform, but the South Korean firm has been working with chipmaker Intel to develop Tizen as an alternative operating system.

It is seen as a way to make Samsung less dependent on Android's developer, Google.

"It enables Samsung to hedge its bets much better compared to some of its rivals," Andrew Milroy, a vice president with consulting firm Frost & Sullivan, told the BBC.

"However, it is unlikely to make a significant dent on the Android market share."

The company will show off the phone at the Tizen Developer Conference, being held this week in San Francisco.

It did not disclose the device's price.

Samsung is currently the world's best-selling Android device manufacturer.

However, many other rivals such as HTC, Sony, LG and Huawei also use the operating system to power some of their devices.

As the competition in the smartphone sector increases, and growth rates slow, Samsung has been looking at ways to maintain its lead over rivals.

One of the areas that Samsung has been working on is Tizen - a new open source operating system for its gadgets.

"Samsung is seeking to integrate its own components, displays, software and services," said Ian Fogg from the IHS consultancy.
