I'm wondering if this has to do with bluetooth issues. My iPhone Plus 7 has issues with drop out while using bluetooth and doing anything (Facebook, Safari, flipping through the home screens, etc) while listening to music in the background. My car and my Bose QC35 experience this. Its almost as if there's a CPU issue with something (bluetooth driver?) that is maxing out and dropping the BT stream. The song position is not affected - it seems to move on as if nothing has happened. Was hoping 10.1 would fix this, but evidently not... Is it related to the new wireless chipset in the new phones?
