Ive been having this weird sound messing up all my videos and I just figured out what it is. My phone does not autofocus during video recording so I think something is wrong with my sensor. The weird thing is that it autofocuses when im not recording video. (before hitting record) Does anyone else phone do this? I'm going to try a restore but next stop is apple store I guess. If you DONT have autofocusing problems during video recording dont be afraid to chime in. By autofocus I mean does it focus on its own? The only way I can get mine to focus is by tapping.
