Still on stock android & you ask why? Maybe it's because grapheneos is only compatable with a small amount of phones & all the phones everyones got = no compatibility. They should either work on being more compatable with more phones or make their own phone with the os on it. Who wants to go buy some old pixels or old samsungs just for this?

You can install it on a new pixel. You don't need an old one.

I don't have a pixel & I don't think pixel 11 pro is supported yet. Pixels suck anyways they were made for right handed people. Need more brands compatable.

New and happy customer here... Left iOS after 15 years and won't go back

It does you just can't buy it yet. Will be public at later date.
