You could also use F-Droid, specially along with some of the alternative repos like IzzyOnDroid and Guardian project, it's pretty much big tech free. I've been on @GrapheneOS for couple of months now, good stuff!
Discussion
In various Youtube videos people are talking about security concerns with F-Droid.
For now I try to stick with applications from source (Obtanium) and Zapstore, as I like the idea with the social graph
Huh!? What security concerns? The whole F-Droid pipeline is open source and verifiable. Either there's a vulnerability that's been discovered and is being worked on, or whoever is making these claims are fear mongering for some other reason.
