First time ive noticed this with my Droid X just wondering if I should bring it to Verizon. When I have my volume at high it seems the speaker is vibrating much like a busted speaker or old phone does. I have to lower the sound to say 50% to hear clearly without the vibration. Is this normal? Ive always had the volume on high every phone Ive ever had, im always on my car dock listening through my speakers so I dont usually talk on the phone directly most of the time, but I was having a conversation and I noticed this today.
