Moving back to CM12 Official.
Sorry guys but there is definitely something strange going on with the camera... Even with the recommended wipe Cache/Dalvik. That temporarily fixes the problem but it soon returns with "cannot connect to camera" in other apps. The phone runs too hot after the error then drains battery really bad.
Please don't get cross, Just wanted to give you the information so you can look into a fix as apart from the camera this is an excellent ROM.
I'll check back in the near future to see how the ROM is getting along.
