cm13 on K30-W from Ed300 with camera issue

Hello, i have recently installed the CM13 from ED300 on my K30-W. Installing Open Gapps pico isn't possible and shows some fails of ending services. I have reinstalled after complete wipe without Gapps. All works fine, until I installed some Apps like Whatsapp, and others the device isn' t recognizing the main camera. In CM11 from ED300 I had the same problem. On Stockton there was no issue with the camera. Can anyone help me with this problem, please?
I have made no backup of the stockrom. Stupid, I know.
Thanx for your help!!!
