Recently I noticed that when my phone (Huawei Ascend G610) autofocuses, I hear a "click" sound coming from the rear camera. Some say it's normal because it is due to the camera lens moving ,which I'm aware of, and some say it might be a hardware defect. It feels uncomfortable and annoying especially during video recording because the "clicks" are also recorded by the video. My phone is just a little over 3 months old. Please help me. Thanks.
