I don't know what happened but my galaxy S2 from att started making a weird buzzing sound when I turn on the camera or use the flash light app I haven't dropped it in water or anything.... I just installed a camera app and this happened, uninstallEd and it's still making that noise. Its like.... bzzzzzzzz. I can hear it from camera, and when I put my finger near it I can feel the tiny vibration of the buzz... I'm so scared cause I don't have insurance.
