I searched the forums and I couldn't specifically find this issue. I noticed yesterday that when I use a bluetooth headset with my LTE Nexus, it has sort of a squealing or buzzing sound. It's almost likely some sort of interference. It can't be heard on the other person's end, just mine. The headset itself works fine. Also, the noise only happens during a call, so if I'm just sitting with the ear piece in my ear, everything is quiet. I haven't had a chance to do much testing with it just yet. I did verify that the same bluetooth headset has no issues with another phone. Later today, I may try testing another headset with my phone just to see what happens.
As bad as I hate to, I think I may restore it back to factory to see if that helps. Everything on the device is stock, but it is rooted. Anyone else experiencing this issue?
