Changes

Partially open source, developed by Finnish company Jolla and the Sailfish OS community. Licensed devices come with a (proprietary) Android compatibility layer as a stop-gap solution to the relatively small amount of native apps. Though it contains many proprietary parts, the community has ported the OS to a variety of existing devices beyond those sold by Jolla.

microG GmsCore is a free and open implementation of the Google Play Services Framework. It allows applications calling proprietary Google APIs to run on AOSP-based ROMs like Replicant and LineageOS. Acting as a replacement for the closed-source Google Apps (GAPPS), it is a powerful tool to reclaim your privacy while enjoying Android core features.
