Samsung LPU9D USB always on if light sensor is on

[KingInTheNorth]

Hello
I have found a some sort of bug in my projector LPU9D. 

I have a motorized screen that has a usb dongle to be connected to the projector for  automatic reveal/disappear. So, in normal situation it works correctly ( when projector turns on, the screen appears and when the projectors goes off, the screen disappears ).

Then, through the SmartThings app, I turned the built-in light sensor of the projector on to use it for a home routine to control the lights in the home if the light intensity is higher than a specific amount. But I observed than when this light sensor is on, the USB port on the device stays always on even when you turn the projector off.  This results in my screen to not disappear when I turn the projector off.

I guess this is something that Samsung development team should address in future updates.

Regards
