Version of 18-11: not bad... almost usable, but I have seen some issues:
- GPS is invisible for myTracks... a few other application (Endomondo, g:hu) works fine, but myTracks says: no GPS device at all!
- Still a bit slower (than in GB) changing the applications
- After a few hours it has been frozen when I open the Nova launchers menu. There was also a very slow period, when all worked, but with some 10 seconds of waits!
Go to GPS defenitions and in Source of GPS see if you got the Use Internal GPS active.
