razer phone 2 camera fault

Hi, I have a razer phone 2, bought new, had about 2 months and love it appart from an irritating issue with the camera, if I go to zoom whilst the camera is open I get an annoying buzzing sound from the camera it's self, if I enter into portrait mode on the camera, the image is blurry and the noise continues and does not stop until I boot the phone down. I'm assuming this sounds like a mechanical fault and not software......any suggestions!?
