On zooming in or out while using Camera, a weird rattling noise along with vibration and humming sound occurs from the Note 9 cam lens! The whole picture gets wavy and blurred. It almost makes the camera unusable. It specially occurs on zooming 2x or 5x or 10x and at times while using Live focus. Sometimes the camera works fine, while some odd day it starts rattling back again. Another instance of its occurence is when phone gets heated. I've to either switch it off or let it cool down.
