Same issue here, the camera is buzzing past 2X zoom and is impossible to use live focus, this happens only with camera app, not a problem when I zoom with 3rd party apps
I'm from Indonesia and have the same problem with my note 9 too !
Suddenly today when I used camera and zoomed it. The motor buzzing so loud, focusing become slower when use zoom, and I can feel the vibration when hold it.
I hope samsung improve their quality because note 9 is their one of the great flagship phone and must worth with the price too (because it's expensive)
Hi I bought my note 9 just before last Christmas, whenever I zoom in using video mode my camera starts buzzing like an angry wasp is stuck in there and the screen goes all wavy like looking at something on a really hot day?
