define which camera to take LightSensor input

[taewonyara]

I am assuming the light sensor value is being derived from the camera.

I've noticed that the light sensor derives values from the front camera of the phone.

Is it possible to define whether to use the front or back camera of the phone? or is it just the case the light sensor is situated there? The latter would also make sense as that's what the device would be using to calibrate the screen brightness
