Android – Camera LED broken

I have an LG G5, and my front facing camera LED (notification LED) is broken.

Camera apps I have tried now take a long time to initialize and I get ‘serious camera error’ when I try to use the front facing. Every so often it does work though; so I know the camera is fine.

Does anyone have any clever methods of disabling the LED/checking? I am rooted & have TWRP.
