It is somewhat ironic, though GrapheneOS onlysupports Pixel phones. Having messed around with custom Android ROMs before, I can understand why the dev team are choosing a narrow selection of devices to maintain builds for. Just take a look at how many different Samsung phones there are out there - it would be a nightmare to try and support all of them!
Even though you’re saying install GrapheneOS, it still seems a bit odd to suggest a Google Pixel 😆

It’s one of the closest devices to AOSP spec, so not a bad starting point for Android, regardless of flavor.
