I'm running 7.0.1 on my 5S and the center headphone button doesn't seem to be working. The volume controls work perfectly fine and I'm having this issue on multiple pairs of headphones. Is anyone else having this problem and have a possible fix?
A few days ago, I noticed I couldn't start music by pressing the middle button as you could before. I had to start the music via the phone to be able to pause/play with the middle button.
