For a couple months the camera on my Curve 8330 has just shown a black screen. Sometimes I would get a message telling me that "camera could not start and to close other applications"...(there were no apps open).
I tried everything from battery pull to updating all software to changing SD cards...and of course NOTHING WORKED!!
FINALLY, PROBLEM SOLVED!!! Solution??
Go into the options on your BB web browser > click Cache Operations > Clear ALL history > Re-boot device and BAM! Just like that! WORKING CAMERA!
I cant tell you how many people told me that I had to send it back and blah, blah, blah, blah....
I don't understand how deleting history or clearing cache would cause the cam to start or stop working. Not unless you are super low on mem. But hey. Atleast its working now so I'm glad 4 ya
