I think I may have some lint stuck in the microphone port, and I'm wondering if there is an easy way to clean that out that I'm not thinking of. At least, I hope that this is the issue. See, when I'm talking to someone on the phone, they can't hear me very well at all; my voice seems very quiet and I have to speak very loudly in order to be heard. This goes for placed calls, and calls received. When I am on speakerphone, they can hear me just fine! Also, when I blow gently but directly into the mic, it registers pretty well on the other end of the line. I've heard some pretty varied theories as to why this is happening. Software issue related to the sim card; problem with the towers; the phone thinking that a headset is plugged in; etc. Again, I'd like to think that my problem is a lint-filled mic port. Anyone else having this problem, while we're on topic? I'd love to avoid experimenting with factory reset.
