Camera rattling noise

I now had the Galaxy S6 for several months and I found this phone totally awesome, but a few days earlier it started a rattling noise from the camera. Most of the time I open the camera app, it makes a strange sound (like it is trying to move the lens and the motor fails it to do so). When the camera is open and I try to refocus anything from very near to very far at once, it sometimes make that awful sound too. I am bothered, because I rooted my device some months ago, installed custom kernel and so on. Can I take this to the warranty or am I screwed? Should I bother about this sound? Will it get worse maybe?

Thanks for any help.
