My iPhone 5s's EarPods button stopped working
My iPhone 5s 's EarPods's buttons stopped working today. The mic and sound are perfectly fine, but the volume and central control doesn't anymore. It was working fine this morning and then I dropped my phone from my desk to the floor. The phone works just fine with out a scratch, but the buttons are not working anymore. Is it because of the jack? what should I do?
iPhone 5s, iOS 7.1.2
