@m0xee @safiuddinkhan @cyberspook @iska @dushman Not exactly. Don't be part of the FOSS cult and you'll be just fine. The reason GrapheneOS only supports Pixels is because they are extremely sane with security and allow you to even sign your own OS with your own key which at that point even Google can't get it, because it's yours, just like a PGP key.
Not a single other phone allows you to do that. GOS knows their shit, and it's the reason I only use Pixels. I want real security and privacy, not fairy tales. Fairphone even signs their OS with Google's publicly available test key... as their private signing key.
actually I believe OnePlus also allows custom signing keys (however not all models have an unlockable bootloader)
