Today I was listening to some music with and external speaker plugged into to the headphones jack when I got a phone call. I unugged the speaker, took the call then when I plugged the speaker back into there was a VERY LOUD POP from the external speaker. Now NOTHING workes in the headfone jack. The external speaker works just fine in other devices. I have tryed 3 other external speakers into the phone and NONE of them work. I see others are having simalar problems but I cant seem to find a solution. Can anyone help?
