grayway2 no, that's not entirely accurate. The GrapheneOS project has said that it will "eventually" be preinstalled, not that it would happen immediately. See: https://xcancel.com/GrapheneOS/status/1966190921080266774#m
the new devices we're working towards with an OEM partner will eventually be able to come that way.

Details about GrapheneOS being sold preinstalled, etc. are not determined. It can expand over time.

This would be another mainstream device where GrapheneOS could be installed on it. We're hopeful we'll at least get to that point. Whether or not the OEM wants to sell devices with GrapheneOS preinstalled and provide green boot state support, etc. is beyond the basics we want.
