Recently I've been having a problem with my speaker. When I get a call and push the speaker button, callers can hear me but I can't hear them. Also, when I go to listen to music or watch a video, there is no sound unless I push the speaker button and it plays thru the handset versus the speakers, which sucks. Please help! I miss hearing my BB actually ring, use my speakerphone, and listen to music without headphones.
