Why? Is development-related talk now considered offtopic on XDAs development forum?
I had got rid of the dlopen errors now, but the camera still didn't work. I checked the logcat, there's no missing symbol / lib file. What i found is that the camera HAL nodule can't be loaded. Any suggestion?
EDIT: Is this could be relating to SELinux? Just curious.
EDIT2: I found that there's a missing library file, so i copied camera.msm8974.so from sony 4.4.4 into /system/lib/hw. That seem to fix the problem.
EDIT3: Here's the log with the file included: http://imgur.com/YmmWyof
Please post the logcat on pastebin - a screenshot is not really readable and missing a lot of other output.
If it was an SELinux issue, you'd see some messages in the kernel log (dmesg) but maybe some other lib is missing: in the worst case, you could attach strace to init and kill system_server to see if it (silently) fails to load some camera related library.
