@Wetrix @mistermonster AOSP is just Android Open Source Project, it's just what every Android version ever is based on. It is not private, as its still stock android. Android as a whole loosely uses some Linux components and is sort of based on Linux in one way or another. If you're looking for mobile privacy, security, and openness, use GrapheneOS, which also uses AOSP as it's base, inheriting the Linux kernel.
