So when I was little, I liked to break stuff I didn't need anymore, so I took a screwdriver to the back camera lens and its completely gone, but going into the camera app it still works and its just very blurry, cause of the lack of the lens. Is that a rear panel replacement? Or a whole rear camera thing? Since that lens seems to be a part of the back panel. I just want to restore it now since I'm going through all my Apple products. Thank you!
