I know that GrapheneOS has a lot of security features that make it basically impossible to compromise your phone. And that it has a lot of control over permissions and has some privacy features. But it also has a Google Services compatibility that would allow you to use Google services, which would allow Google to harvest a lot of data from you; much less data, but still some. Now OSes like CalyxOS or Lineage have microG which in addition to giving you the APIs, it uses less battery and has the ability to use Mozilla network location to stop google from getting that data. CalyxOS and Lineage don’t have the crazy hardening modifications that GrapheneOS has, but Android is already crazy secure compared to something like Windows or Linux without a properly configured SELinux or AppArmor. Why have Graphene over Calyx?
Yeah but those are the issues that I have. The idea is to have a private phone where you don’t have to worry about Google harvesting your data and keeping it forever. But when you have an OS that has all these features and then use the Google services that take all that data, what is the point?
According to the last paragraph here, the spoofing at least in Calyx is limited to only microG. It’s less secure than a sandboxed thing, but I don’t think it’s gonna be that bad.
