Sailfish OS changed its name to Aurora OS in Russia
The mobile operating system Sailfish OS developed by the Finnish company Jolla based on MeeGo was renamed Aurora OS in Russia. Due to poor development, Jolla’s current business is mainly to authorize other companies to use its operating system. In 2016, the Russian company Open Mobile Platform (OMP) was licensed to develop the Russian version of Sailfish OS.

The biggest difference between Aurora OS and Sailfish OS is the stripping of the Android compatibility layer, which means it won’t be able to run Android apps. Aurora OS is mainly used by government departments and state-owned enterprises.
