17 September 2015. The Russian anti-monopoly regulator has found Google guilty of “abusing its dominant market position” in the Russian mobile market. In February of this year, the search engine Yandex asked the regulator to investigate Google over whether its Android operating system was unfairly blocking other search engines on Android phones. Google is set as the default search engine on all Android phones, and handset manufacturers are unable to preinstall alternative search providers. With Android being the most popular operating system in Russia, accounting for 86% of all Russian smartphones, Yandex was concerned that Google’s practices were unfair and illegal under Russia’s antitrust laws. The guilty ruling means these fears were well-founded, with the Russian regulator now having 10 working days to release its full findings. Google may now have to change how it works with smartphone manufacturers, and allow other search engine apps to be preinstalled on Android smartphones. Google may also face a fine, although it is currently unclear whether this will be imposed and how much such a fine would be worth. The search giant is currently facing similar charges in Europe, where it stands accused of deploying tactics to boost the ranking of its own Google Shopping price comparison services, whilst pushing rival services offered by competitors further down the search results by demoting the value of their links or simply refusing to list them altogether.
