Haven't actually talked to anyone on my phone for a couple of days. Well I received a call yesterday and it was near impossible to hear what the person on the other line was saying, even after turning the volume up to 100%.
As a test I called my cousin, 'cause his calls always come in crystal clear. Same problem, almost completely inaudible. I wondered if it could be a hardware problem so I tested it with and earbud, still quiet.
I went through all the settings I could and couldn't find anything. I came here and did some searching for about an hour and a half to two hours. I came up with similar issues, but all different enough to not be able to help me.
I decided to reset the phone by the battery pull method, and viola, the problem was fixed. Don't know what caused it, but it was definately a software issue.
Part of the reason I'm typing this up, is if someone has or will have the exact same issue, they can search and get my experience instead of a bunch of similar issues.
Also, if anyone knows what software issue would cause this, please post up. I'm really interested to know.
One thing I did learn last night however, is this phone has WAY too many settings
