It still boggles my mind that the most popular privacy OS requires Google manufactured hardware, that fact alone makes me not trust it at all.
Phone hardware is a hellscape it doesn’t surprise me at all that they need to keep the number of supported devices small in order to deliver a decent product.
Despite Google's other failings, it was the OG supporter of data portability, and that spirit extends to its phones. No other phone manufacturer with wide distribution comes close. It's unfortunate that the people who design the hardware do such a poor job with the resources at their disposal.
It's ridiculous is what it is. It makes me deeply distrustful of the organisation behind Graphene that they would make such a crazy choice.
They list their exact criteria for supporting a device. So far, only Pixels fit all of them (and I guess the Motorolas will soon)
