good point with the second device, still much better than being tracked by Google or with most recent news Apple Siri ;)

I had in mind those going after fancy folding phones

the top tier phones are shipped with the ai and soon everything else will have it all way down to the low price range so the best solution is to have GraphenOS device instead but not every phone out there can handle it outside of pixel family just yet.

I went through the link you shared

https://grapheneos.org/faq#future-devices

it makes a lot of sense indeed
