[Edit] Problem solved. You can ignore the following post. The camera is working with the XXKPO baseband!
i flashed XXKPO in recovery. Since then my camera (aosp & google) can't safe photos anymore. The pictures are taken but not saved. It worked with XXKPK before,
I am using CM11-20140808-UNOFFICIAL-dev_connection_team_arievse
Things i tried:
1. factory reset
2. download baseband zip a second time, flash the new file
3. installing CM rom image again
Non of these efforts made a change.
I was thinking about formatting the internal sd-card, but i haven't done this yet, because i have no difficulties to write on this partition.
Does anyone have an idea, what caused this strange behavior?
