GrapheneOS is finally ready to break free from Pixels, and it may never look back
(www.androidauthority.com)
There are definitely some things that do not work with GrapheneOS, though most haven't affected me as I don't use them (like banking apps).
- A lot of banking apps don't work, especially from some European banks. I believe there is a fairly well updated list available online.
- Android Auto can be made to work, but it's quirky and you have to fiddle with quite a few settings and possibly give up a fair amount of privacy to get some things going (like navigation). I'm still fighting with this.
- Many apps will initially not work until you figure out what permissions they actually need and which they can bend on.
I still personally think it is worth it, but I can only speak for myself.
