Here you go..
Tested it, without luck.
Don't know if I did the right thing?:
- Downloaded the newest zImage. (2013 03 23)
- replaced the zImage from /system/bootmenu/2nd-boot with a file manager
- restarted the phone
- opened photo camera: Black screen until message "not responding, Close/wait"
- opened video camera: Black screen until message "not responding, Close/wait"
I added dmesg and logcat.
Can you check if camera0 is present in /dev/camera0?
