Just wondering, why wouldn’t you want to run Android? AOSP is fully open source, google free, and runs on linux anyways, these other OSs are just bound to be buggier…
As far as I know, AOSP is largely maintained by Google. Without the Google Play Services you lose key functionalities such as notification service or the ability to use home banking apps.
While alternative play services such as microG exist, in my personal experience they are buggy as hell. My banking apps continued not to work and notifications were often delayed by several hours.
I’d love a real opensource linux alternative driven by the community without a big tech dictating what goes in or not. We’re not there yet but it’s cool to see people trying.
Will online banking services work on whatever OS this device in the OP uses? It seems pretty unlikely.
