Do Google Pixel phones come installed with GrapheneOS? We’re talking about custom setups with more privacy here.
I did have to follow the installation instructions, which included unlocking my bootloader, installing adb on my PC, and entering a few command lines.
There is the possibility to buy it preinstalled though, but from a third-party company.
It’s because Graphene is not a custom ROM. /e/os is. Graphene is just an OS on top of the ROM, and Fairphone doesn’t update their ROM often enough.
This is a complete non-issue though if you use a custom ROM like LineagOS or /e/os.
