Graphene OS

There's an Android alternative operating systems that you can install on your Google Pixel if you don't want to use android. It's called Graphene OS, I wish other Android devices were compatible with the OS but they're not. There are rumors that the people behind the OS are working on getting phones shipped with the OS already installed, so you don't have to get a Pixel and flash it yourself. Do you currently use this OS on your phone?
