I just got my droid and it make kind of a fast pulse quiet mini high pitch beeps when the camera gets turned on. It also does it when I switch out of preview after deleting a picture to take another picture. Its not the shutter sound because the shutter sound different(I can hear what the shutter sounds like when i press shoot button halfway down). Is this phone defective?? It seems fine otherwise(green focus). My phone is 39/09
