Since when did you have the problem? I'm like 99% sure that it is CSSU related. I did a reflash yesterday because the new camera-ui wasn't (and isn't) working for me. I reinstalled all apps but forgot to test fcam before i reinstalled the CSSU... Anyone else with the closing camera-ui problem who fixed it? EDIT: Got it working by opening the camera app with lens cover closed and setting "Storage" to sd card. for me it was "mmc-undefined-name"
