When I take calls there is an annoying crackling sound on the Gnex earpiece speaker, but NOT with the external speaker when I put it on speakerphone. It sounds like the speaker itself is rattling or something. Did not do this on my D1 and our other phones (iphones) do not sound like this. This gets better if I lower the volume to about half volume, but then it is too soft to hear well. The external speaker is fine and bluetooth to the car is fine so I presume it is the speaker itself. I do have volume+ paid version. The speaker setting is at +6, but the headset setting is disabled, bluetooth setting disabled. Has anyone else noticed this? I noted some posts on the Razr forums but not on the GNex.
