I'm one of the ones that tried everything and couldn't get enough sound during a call. I purposely moved the speaker at the very top edge of the phone all around my ear while on several calls and bottom line is even when I found the loudest position, it wasn't loud enough. I did find the position where the very top of the phone where the ear speaker is located was directly on top of my ear canal. It certainly seemed odd compared to all of my previous phones where the ear speaker is slightly below the top edge. In any case, it was not loud enough, and I'm smart enough to know to move the phone around all over the place to get it at it's loudest point on my ear. I can't even believe someone wouldn't try that before complaining about the poor call volume. The phone just didn't have enough volume, plain and simple.
