In a comment on Reddit, the team behind GrapheneOS has confirmed plans to start offering devices other than Google Pixel smartphones at a “similar” price. These Snapdragon-powered devices are coming from “a major OEM” that remains unnamed in the post.

GrapheneOS will drop Google Pixel exclusivity with 'major' Snapdragon-powered devices coming

@privacyguides I see it may be OnePlus, although can't confirm. Would be awesome, I like OnePlus's hardware personally. I currently do run LineageOS on the OnePlus 11 5G. That reminds me, I need to update it to LineageOS 23.0 today.
@korbs @privacyguides If I had to bet on an OEM, I'd choose Nothing. It's a pretty small brand and, importantly, independent (OnePlus belongs to Oppo, so any potential cooperation with GrapheneOS would probably need their approval). It's also relatively open to the community. On top of that, they have a small number of models, which would make such cooperation much easier. And of course, all of them use Snapdragon chips.
@ppaluchowski64 If it's Nothing, that could extend into CMF phones as well. Would be interesting to see.
@korbs That would be great, but unfortunately CMF phones don't use Snapdragon chips - which are already a bit of a compromise in terms of security, since their secure elements aren't as strong as Titan M2, the dedicated chip used in Pixel phones.
