It’s barbones Android, without the Google. You can add the Google stuff if you want, but by default, it comes completely de-Googled.
It also comes with some extra features, like granular app-level permissions, sandboxed Google Play Services (which a lotta apps use), duress PIN, and more.
Widely regarded as the safest and most private “commercial” mobile operating system.
Disclaimer: I run SwapMyOS, a GrapheneOS/custom ROM installation service.








Even though it’s not technically physical, GrapheneOS does have switches for both the camera and mic that disable them at the system level.
So if you answer a call, for example, you’re prompted to unblock the mic because the phone app is requesting to use the mic.
