       1. My phone does not have a backlight function   

       2. A device that beams light is already widely available, under the name "torch", "flashlight" or "lamp". Most of these such devices are capable of being placed on the ground.

       I was thinking more of a rotating device that lasers light into a hole on the back of the phone that can be reflected by prisms behind the screen
