On a Pixel from 6 upwards? Absolutely. GrapheneOS is what Android should be in terms of privacy and security. Its major drawback is only being available on Pixels, but if that is what you have…

I bought my Pixel 6 specifically to run GrapheneOS, and I really hope I can repeat that for my next device.

GrapheneOS is by far the better OS security and privacy wise.

It should be the default choice for everyone IMO, as long as they have a phone that supports it.

See this comparison: https://eylenburg.github.io/android_comparison.htm

My rule is: if you can run GrapheneOS, you should run GrapheneOS.

My second rule is: if you are buying a new phone and can afford one that supports GrapheneOS (at the moment it means a Pixel), then you should go for that.

I haven't used LineageOS for a long time, but I remember it being really good. And I used cyanogenmod which IIRC was it's predecessor.

GraapheneOS is a different ball game IMO, especially if you need to use Google play services etc, banking apps etc. I'm not sure what the current state of microg is or Google services on lineage.

I bought a second hand pixel 6, just for Graphene and when that died I bought another pixel.

(I strongly disagree)

That's not helpful without context and substance.

They have access to the patches.

They just can't make an official release with it, because they can't publish the patch sources (embargoed) and their releases being open-source must match what they published...

What if that OEM stops giving them patches?

Also, if they're asking an OEM to release the patches, why can't they become an OEM to do that?

They have an OEM partner right now who funnels them the updates, which is how they get access to them.
