I was just streaming netflix in the car, data was getting spotty so I went to turn 4G off. During the silence I could here the "buzzing", as soon as 4G switched to 3G it quite .. hmmm
So back to 4G and the buzzing comes back.
Just figured I would post my findings. Not really bothering me as long as sound is present but during quietness kinda irritating.
