content: 7f41                     Wouldn't you have to be running a custom android mod also?  Just to use f-droid, no, but if you want to lessen Google's surveillance, yes. The issue lies I think with things like Google's 'Service Core', which projects like https://microg.org/ try and replace (some apps need it). Micro-g though is ultimately just a patch, and has you tied to google. Ideally, you'd just get f-droid and a de-googled custom ROM, since you don't necessarily need any of that. That or you could ditch android entirely for a mobile linux distro.
