I don't know whether it's anything to do with it, but since updating my iPhone 4S to iOS 6.2, I very rarely get any audible notifications that I have an incoming text or call!
Sometimes it works. but most of the time it doesn't and it is most frustrating as sometimes it's several days after that I realise that I've missed important a texts and answer phone messages as my phone doesn't let me know that new texts or calls have been made!
Can someone please help?
