I was trying to do a poll on how many people actually had this buzzing issue when the phone vibrates. The problem seems to be very widespread and common. Talked to a genius and they said they never noticed the issue before but when he looked for it in comparison to mine he noticed and everyone with a phone in the back room had it or was louder. He wouldn't swap it out but said I could get a new one through reserving so that's what I'm doing. I don't want to keep wasting my time swapping out phones if a vast majority of the phones have this buzzing. He even said that if you don't notice it now it will probably show up later.
