Which is better than nothing but I can't help but see it as walking into another exclusive partnership. Also, none of those phones are out yet so I'll believe it when I see it.

Even if it pans out and there will be one Motorola phone supporting GrapheneOS out of the box in 2027, there's the issue of how much it will cost (I think it's supposed to be a "flagship"), what markets it will be available in, what the unlock process and conditions will be like etc.

Last but not least I doubt Lenovo's commitment to "seven years of proper updates", which I will also believe when I see. Their track record for Android updates is notoriously poor. They claim 3-5 major Android updates for most of their models but the best I've actually seen them do is one update (13 to 14) – and that's for phones released 2-3 years ago. If that's the pace they wanna go we'll be lucky to get two updates in those 7 years.

On their flagship phones.

Because it supports it in hardware. But I agree, that should be optional which would make Graphene available on many other devices.
