microG works well as a substitute for the Google Play Services client. I generally don't have issues with banking apps on microG, though people using apps for banks based in other regions might have different experiences. Navigation, music streaming, Microsoft Teams, Slack, rideshare, and public transit apps work flawlessly. Push messaging is fully functional. As a bonus, microG does not implement any of the advertising features in Google Play Services.

Operating systems that have microG preinstalled include CalyxOS, /e/, and LineageOS for microG.
