MOSCOW, Nov. 25, 2011 (GLOBE NEWSWIRE) -- Yandex (Nasdaq:YNDX) has
become the default search engine on Windows Phone-based handsets in
Russia. The company has partnered with Nokia, Samsung, HTC and
Microsoft to provide its search services on the latest Windows Phone
smartphone models on the country's mobile market.

Yandex's search engine is now installed on Samsung's Оmnia W as
well as on Nokia's Windows Phone-powered Lumia 800 and Lumia 710. The
Samsung Оmnia W is already available for purchase in Russia.
Nokia's smartphones will hit the stores in December. Also, following
the launch of Windows Phone-based Titan, Mozart and Radar smartphones
last autumn, HTC is planning an update release with Yandex as the
default search engine on its handsets.

"Windows Phone is a new operating system with great potential. It is
bound to catch attention in Russia. It's good to know that the Windows
Phone users in this country will have familiar Yandex search on their
new devices," says Tigran Khudaverdyan, Head of Web Portal and Mobile
Services at Yandex. "The range of apps we have already developed for
this platform includes Yandex.Maps and Yandex.Market and we will
continue our effort to expand this range."

"Launching Windows Phone in Russia, our goal was to provide our
customers in this country with the latest version of a mobile operating
system integrated with the most popular local web services and social
networks. Now we are pleased to announce that the services of our
strategic partner Yandex will appear on a wide range of smartphones
supporting Windows Phone," says Anna Kulashova, Director of Mobile
Carriers and Service Providers Development at Microsoft.

Yandex develops apps and services for all major mobile operating
systems. In October 2011, Yandex became the main search provider on
bada-powered smartphones available in Russia and the CIS.
