I got this iPhone 5s stuck in headphone mode even if the headphones are not plug in. When I play YouTube videos there’s no sound and when I press volume buttons it say headphones. I did tried a new charging port still not working,I think it’s something in the motherboard,maybe a chip or filter. Is anybody had this issue before or fixed anything like this. Please let me know,I will gladly appreciate your help.
I have never run into this problem specifically on an iPhone 5s. However, (assuming you’ve already power cycled the phone) I would plug in a pair of headphones and unplug them first. If the problem persists do a backup and restore. Let me know if you have any questions. Thanks, CW
