I used GrapheneOS as a daily driver for about two months on my Pixel 7. I ended up having to switch back:

1. RCS messaging just doesn't work. No matter what I tried, RCS would never connect so all texts were being sent OTA in the clear - not great when using a security-focused OS.
2. Notifications just stopped working despite permissions being in place. Apps with all permissions just did not send notifications.
3. Apps that rely on background updates do not update unless manually opened.
4. Calls went straight to voicemail after my first web-based USB install - I reflashed GrapheneOS and the issue went away for a little while, then returned.
5. Less control over my phone's settings than I have in stock Android.

It's a good idea and I wanted it to work, but it's still just not stable nor ready for daily use.

Per https://phiresky.github.io/lemmy-federation-state/site?domain=daring.lemmy.fan it still appears that federation is lagging with 0.19.0-rc.1 Looks like federation is indeed working.

Test posting from https://daring.lemmy.fan running 0.19.0-rc.1 to check federation.

I feel this so much.
