Phone calls are fine, good quality, BT works, including PBAP (with 2.0.4, there were problems in 2.0.3.x). The only issue I have is the home screen freezing, but that's a problem with all phones with 2.0.4. Stopping LPM minimizes that. BT is disabled after reboot, you need to manually start it (adaptation problem).

Now that the browser has newer engine it is much more usable and I don't miss the Android apps from Jolla One so much.

Camera works rather good, though sometimes after update it doesn't show the viewfinder for some reason - a restart fixes that. There is also a patch from kimmoli, that enables 4K for video, didn't use it yet.

Can't be used with multirom though.
