If I install Lineage OS on a phone that’s still supported, can I pretty much assume that I can then install f-droid? Also, before I take the plunge, how can I see what apps are available in f-droid?
Edit 1: I am also trying to understand what are typical things that people install after installing the OS? There are multiple “play store” like programs, right?
Edit2 (5/26/19): It seems as though there are “variations” of the ROMs. I came across LineageOS for microG. Are there others besides that?
You can install F-Droid on any Android system, since it’s a normal app. But if you have a custom ROM, then you most probably have a working custom recovery, and that enables you to integrate F-Droid with your system through the Privileged Extension, which comes quite handy.
