Russian search company Yandex filed a complaint with the board in 2015, alleging that Google requires smartphone manufacturers to pre-load Google Play Store, Google Play Services and Google Mobile Services on any Android devices they sell, and to make Google Search the default search provider on those devices. Such behavior would be a concern for Yandex, which offers app store, mobile mapping and search services of its own. Yandex had filed similar complaints against Google elsewhere too, including in Russia and the European Union, while a similar case in the US was triggered by other complainants. The Turkish complaint fizzled in December 2015, when the competition regulator ruled that there was no need for an inquiry since smartphone buyers were free to download other applications to the devices they purchased. Unhappy with the ruling, Yandex appealed to the Ankara District Administrative Court, which in October 2016 suspended the board's initial ruling.
