Hey guys. I just upgraded from an S3 to an S5 a few days ago and I'm loving it so far. One thing that's bugging me though is that whenever I'm using my phone as an actual phone (Who actually makes phone calls anymore, right?!) there is an annoying buzzing/rattling/almost kind of like distortion) when the person is talking to me. It usually goes away if I turn the volume almost all the way down, but this is obviously not a practical option since I'm not always making phone calls in a dead silent room. The speaker phone works fine. This only happens when I'm using the earpiece. Is this normal? Is it related to the camera autofocus sensor rattle? Are the sound vibrations from a person's voice enough to set off the rattle? It's really annoying as I tend to make phone calls a lot and I don't like using speaker phone or a headset. Does anyone else have this problem? This was never an issue on my S3.
