The petition for Google has been initiated by Anatol Taranau.
The petition is very brief. It simply says that it would be good to introduce a Belarusian interface for the Android operation system. Taranau also noted that the Russian language was default for all Belarusian smart phones. But many people would like to use Android in Belarusian.
About 500 people signed the petition in change.org in 13 hours as of February 19. It will be sent to the Google corporation if at least 10 thousand people sign it.
