What is this list, that has no equivalent in Android/AOSP in general? Storage scope existed since Android 10, when GSF was introduced separately from native storage access. I have no clue when they claimed to "invent" contact scope, but a different user account (like work profile) segregates everything from storage to network tunnel to contact storage, and user accounts have existed for 10ish years. Disabling all userspace apps is possible on all Android phones as well, just not system apps, for which you need a computer and ADB/Shizuku API access, all of which can be done without rooting or a special "custom ROM".

While the storage scopes ability has been there since Android 10, I have never seen the level of granilarity by app that GrapheneOS provides anywhere else, which justifies the mentiin of it on GrapheneOS. I never said that they invented Contacts scope, and I am not aware if this is their doing or someone else's. The ability to choose scoped content by app is super convenient, and IMO more straightforward than using different accounts for this purpose. Now, having segregated profiles for the apps that I know I need and have no way of replacing with a "trackerless" alternative (such as my Aruba InstantOn app) is a Godsent, no doubt. Using ADB is not for the faint of heart, we all know the capacity of damage it has if used carelessly, and punching a hole with Shizuku does expand the vulnerable attack surface, specially since it enables those holes over WiFi.

CalyxOS. Even LineageOS is fine. Even not putting one of these things on your phone, and doing things non-rooted (my guide) via ADB/Shizuku on any Android phone in the past 5 years is going to be fine. An exceedingly more important (99% as you say) thing is the user, them forming a proper OPSEC, and not making OPSEC mistakes.

If you could shqre your guide, I'd appreciate it. I am paranoid about using Shizuku or any other type of hole punching method.

These AOSP forks are tools, and all of these open source tools are uncompromised, that is a common theme. Tools do not really matter at this point if you use any of them. It is like picking any Linux distro. You are pretty much safe from telemetry and spyware immediately compared to a vanilla Windows installation, the moment you pick a distro.

I'm 100% in agreement with you in this comment. Any Linux distro will remove almost all risk of telemetry or spyware when we choose to move away from Windows or Mac, unless you opt-in to some telemetry on avfew, like Ubuntu, and even then, the difference is night and day.

I never played that game, but I can only imagine the frustration. Sorry you went through that.
