iPhone 5 suddenly will not ring or vibrate for incoming calls.
All of a sudden I realized my phone was not interrupting me if I was listening to music on the headphones. The phone is not registering missed calls either. the only way I know if someone called is if they leave a voicemail. DNd is not turned on. Ringer is on volume is up. I use headphones because I have a hard time hearing. I have had iPhones for years and never had a problem like this before! Help!!!!!!
iPhone 5, iOS 8
