We have a partial port of GrapheneOS to the Pixel 11 series after a week of work on it. We're unable to complete the port due to lack of support for ARM hardware memory tagging in software, firmware and near certainly hardware. It appears Google cut an important security feature to save money.
They are compatible with some existing and future phones. Google’s in-house processor decided to skip on an extension that the broader ARM ecosystem seems to continue to value. Graphene didn’t invent this extension. I presume that their compatibility with upcoming motorola devices indicates other mobile device processor designs implement the extension just fine.
When you are so, so good at security that your OS is compatible with 0 phones. Well done Graphene team.

No one can hack your users when you don’t have any.
