		* The torchStrength value must be within the valid range i.e. >=1 and

		* When the client calls setTorchMode(ON) after turnOnTorchWithStrengthLevel(N),

		* torch mode. The framework must open the camera device and turn
		* the torch on through the device interface.
		* - This camera device does not have a flash unit.
		* - This camera device has flash unit but does not support torch
		* strength control.
		* CAMERA_DISCONNECTED:
		* An external camera device has been disconnected, and is no longer
