Using iOS 7 on an iPhone 5. Today I noticed that even when not placed on silent, I was not being notified of texts with an audible notification. Checked settings and all were correct. The wife called me and the ring tone played. However, that is the only audible notification I receive. There something else option wise within the OS I am overlooking? Second issue, I'm reminded/notified that an accessory or cable may not work with the phone. What is odd, is there is no cable or accessory connected to the phone when I am receiving these notices.
