The company behind the most widely used search engine in Russia and the ex-Soviet region has recently diversified to defend its market share against Google, creating popular phone apps to order taxis and takeaway food.
"We built Yandex. Phone to offer Russian users a smartphone that is equipped with all the localized tools that help users better navigate their daily routines," Yandex official Fyodor Yezhov was quoted as saying in a press release.
"Within the smartphone, the Yandex apps are presented in the form of an ecosystem with Alice at its centre. It's not necessary to open individual apps to solve a task -- just ask Alice." The phone signals a major new phase in Yandex's development and is designed to rival giants like Apple, Samsung and Huawei.
The smartphone's launch comes after the company last month disappointed tech enthusiasts by summoning journalists to what turned out to be a presentation not of the smartphone but of its smart speaker.
In 2013 the YotaPhone, designed in Russia but also made in China, was launched with the gimmick of having screens on both sides. However, it failed to set the market alight.
