During calls, I sometimes can no longer hear the person I'm talking to and the volume controls say "Ringer (headphones)". I don't know how this happens and cannot figure out how to change it back to normal. Eventually, it returns to the normal ringer and volume controls. Has anyone else experienced this and knows how to correct or prevent this from occuring? Thank you!
I had not had the headphones plugged in since I got it, which was strange. It has done it several times since. I don't know if I'm accidentally pressing a combination of buttons/controls or how it is happening. Thanks for your reply.
im surprised noone has answered this for you, this is a wellknown issue. ive been having this problem too. most of the information if you do a web search says that it happens because there is some fluff stuck in the jack, so that makes it think the something is still plugged in. so the solution is either to keep plugging and unplugging the headphones to clean it out, or to blow in the jack or use compressed air. however, none of this worked for me and it took to an applestore who said that i should do a restore. i just did that, took over an hour, and it didnt work. they said if that didnt work then do a clean restore, and if that didnt work it was a hardware problem. so take your pick of the above solutions. good luck.
