I've had my Reverb for about six weeks. In the last couple of days the volume button has started acting erratically. The major symptom being that I can't turn the volume all the way down. It stops at about 1/4 volume and won't lower any more. I've been able to momentarily fix this by re-starting the phone, and then it works fine for awhile, which makes me think this is not a hardware issue. I've checked for software updates for the phone, but there is none.There doesn't appear to be any firmware updates either. Has anyone else experienced this problem and found a solution?
