In recent months it is becoming far more common for the camera lens OIS mechanism to buzz when I start up the camera. The resulting image is distorted with blurring all over. An audible buzz can be heard if you put your ear to the lens. I have since noticed if you shake the phone gently with the camera off you can hear the lens rattle about, but if the camera is on (with OIS functioning) there is no rattle. I'm just wondering if something has broken inside and this is why I can hear the rattle and this is why occasionally the lens buzzes when power is supplied.
Can anyone with a functioning phone shake it gently to see if a rattle is heard, and if it ceases if the camera is turned on before shaking?
