Q9C 2.5mm jack issue I just picked up my Q9C this past weekend (terrific phone BTW...lots of improvements over the Q1). My problem is: I get a lot of static over the wired jack. I use a wired headset as a backup to my BT. When using it, I get lots of static, especially if the plug is bumped in the slightest fashion. In addition, I get quite a bit of feedback from the mic into my headset. My Q1 never had these issues. Does anyone else have these problems, or is it a defective Q9C? I am still well within my return period, so an exchange should be a problem.
