I have the same setup as Hannen .... Pi 3B+ with a raspi-cam. The cam takes pictures on its own but does not work in OAP. OAP shows a very faint dark blue image slightly visible in the upper corners. I have confirmed that the camera is working but the settings in OAP do not support this camera. The camera WAS FULLY WORKING with excellent color image in 3.3.2beta. The difference is that in the BETA software, there was provided a camera setting for width and height of picture. Before adjusting that setting, it produced the faith dark blue image. After adjusting that setting, the camera worked just fine with a very clear color image. In the RC version of OAP, the setting was removed (it wasn't needed for USB cameras, I guess). Now with the setting gone, the camera no longer works. The issue is NOT with RPI. It is with OAP.
