I recently got a previously owned Nokia 6682. It had some scratches on the faceplate, so I changed it. And soon thereafter, I noticed the earpiece volume was noticably lower. It's tough to hear even at the higest volume. The loudspeaker is fine. I saw another post about the volume being lower after replacing the faceplate with a non-OEM cover. Has anyone else experienced this or have suggestions for increasing the earpiece volume of the 6682? My hearing wasn't so great before. Now I'm struggling a bit! Thanks! Tom :con?
