I wanted to use an alternative mobile OS, but they only support expensive devices like Pixels or outdated models. So I am planning to port some open Android variant. Obviously, all Google Services will be removed and most proprietary apps too. I also want to be able to manually edit permissions and remove Internet access from most of the apps, even open source. It is inconvenient that Android actually has "Internet" permission but doesn't allow the user to revoke it.
I do not need Google Play (a collection of spyware, covertly collecting Wifi points and cell towers location in my country and sending them abroad), I do not need bank apps (I have a laptop for that) so I guess I will be fine. Obviously there will be no developer verification on my device as well, and I mostly use apps from F-Droid anyway.
Good thing about F-Droid is that they build apps themselves and you can always get the sources - unlike Google Play and Apple Store that provide no sources and unlike PyPi/NPM which allows sources to not match the binary distribution.
You do need Google Play, or a suitable replacement, because most android apps won't work without it.
F-Droid apps do not need Google Play Services. OSMand (offline maps) and other apps works without it. Telegram probably should work too, but I did not test.
AI also says that it is possible to have push notifications without Google.
