Ah thank you very much for enlighten me about Graphene OS, that so far the best description I have seen.

Used Aurora before on Android too.

I probably will wait until they find a way to not be dependent on Google services, as I want them to have no data at all, if I have the chance to do it.

Hopefully there will be more alternatives in the future. But we will see where it will go with Google trying to stop side loading.
