Ok I have a question. Does it matter where you battery life is when you want to use a plug in headset. I ask because I let my battery die wanting to condition it. I charged it to about 17 % and on the way home, with the phone charging I plugged in my aux input to my radio and phone. The music would only come out of the phone. The bluetooth FM transmitter worked ok, but not the headphones. The phone did not even show the icon. I got home and tried another pair and it still would not work. The phone was on about 25 % by this time. I tried rebooting twice and nothing. I then turned the phone off removed the battery for about 20 seconds and when I booted back the battery was now up to 32 %. I plugged in the headphones and now they worked and the icon showed. I have read about other issues just wondering if I have a bad headphone jack or if it is software related or maybe even the battery being to low. I downloaded toggleheadset and plan on using this from now on.
