Google’s Android activities came into question again, as the company was fined in Russia and the South Korean regulator confirmed a probe.

Russia’s Federal Antimonopoly Service fined Google RUB438 million ($6.8 million), following a decision last year that the company had violated the country’s laws by requiring device makers preinstall Google apps in order to get access to the Play content catalogue, as well as setting Google as the default search.

Google came under fire in this market due to the presence of a domestic competitor, Yandex, which had looked to offer its own portfolio of Android apps to rival Google. While Yandex was the dominant Russian search engine, it saw its share diminish as traffic shifted to mobile.

Meanwhile, the authorities in South Korea are reported to have acknowledged for the first time that it is investigating Google’s Android activities.

The Korea Fair Trade Commission issued a brief statement confirming the probe, following local reports that the company was set to be cleared of charges. Again, the issue is the pre installation of Google apps on devices, and the impact this has on third-party rivals.

This is not the first time the KFTC has investigated Google and Android: in 2011 it looked at the impact of the US company’s activities in mobile search.

The news comes as the European Commission is also conducting a similar probe.
