The GrapheneOS developers will only consider the devices with the most secure hardware. That used to be Pixel, but due to Google’s plans with Android the developers feel they have no option but to start building their own devices. It’s recently been announced that Motorola are going to be building Graphene devices. 😔 It’s unlikely they will develop for Nothing until their hardware is as secure or offers similar features, such as a switch that physically disconnects the camera and microphone.
