@luana@wetdry.world It will fully support using other operating systems including users making their own builds of GrapheneOS. It's part of our hardware requirements. We'll likely be able to make hardened builds of firmware and drivers which can be released in an official way for easy builds without needing to extract anything from the GrapheneOS or Motorola OS factory images.
I was meaning more of their Android by default phones, like most retailers are going to only sell the android version
they specify the grapheneos devices so I’m assuming they have a dedicated graphene OS product line.
