My in-call volume on the handset is CRAZY loud! I can turn it down as low as it will go while I'm in a call, and it shows the green bar as far as it will go down low.. it's still so loud that I can't keep it up to my ear most of the time. Is there a way to adjust this??? I just got off a call about 30 minutes ago and my ear is still ringing from how loud it was just by someone simply talking on the other line... This has been happening since I got my phone, and I just can't figure out a way to turn it down lower.. Any help would be appreciated. Thanks!
