Any step you take towards greater #privacy is a step in the right direction. However, adding privacy measures on top of stock #android are largely ineffective. Stock Android is pure spyware, and all Google services and apps are spying tools.

It's also not a great idea to download #nostr or #bitcoin apps from the Aurora Store. If the apps are #opensource code, use 'Obtanium' instead, this allows you to download .APKs directly from their GitHub source.

You can still get services like Google Maps and fingerprint unlock working fine, I'm not sure why you'd think they wouldn't work. Uh, #grapheneOS is just a hardened version of Android that's stripped out all the Google shit, but you can still install them back.
