So this might be a long shot and rather silly but is there a way to disable the 3.5 jack on my Lumia Icon? 1. I don't ever really use it and 2. I got a blank plug I am putting into it and when I do this it thinks there is a headset hooked up when there really isn't. Anyone have any ideas? I can't seem to find out if there is a way to do this or not, thanks!
