I have this weird problem with my iPhone 6 Plus. The phone won't play any sounds because it thinks headphones are plugged in while they are not. I can't hear any sounds and can't take any calls - unless I connect headphones. When I disconnect them it goes silent again. I have tried plugging in and out all kinds of headphones, restarting the phone, the usual drill. It also tells me an unauthorized accessory is connected on the lock screen. This is the second time I have had this problem - last time it disappeared by itself. Has anyone experienced and/or fixed this problem?
Here is a video documenting the problem:
