So I am trying to get into these OSes like Graphene, Callyx, e OS…etc. If need be, I will try to de Google the phone too. Anyway, I understand that you can install apps using stores like Amazo, Fdroid, Acrescent, Aurora…etc, instead of relying on Google Play Store.
If an app I need relies on Play Store, then so be it; I think OS like Graphene allows you to run a profile with Google Play stuff?
Otherwise, I can just use apps from Fdroid, Aurora…etc. Say I have Firefox installed from Fdroid and it requires a serious security update, which store will get the update first: the Play Store or they come at the same time even to Fdroid?
Or I am a dev and I need to send an update for my app, where do I send it first?
Usually it has to go through Google’s approval process for the Play store, but others don’t have any such thing, so they’ll be faster.
If you really want them as fast as possible, if the author publishes the apks, you can use Obtainium to fetch them directly without waiting for any store.
