I just went ahead and installed GrapheneOS even without the security patches. Google had dropped support I believe so I figured I wasn’t losing much/anything.

Being greeted by an out-of-date warning on boot is fun though.

Thanks for the reply! I’ve since installed GrapheneOS and have been looking around it a little. Could you tell me about your experience using different Launchers? Is it a preference thing or are there features of default GrapheneOS that people don’t like?
