I have an iPhone 4 and about a week ago for whatever reason my texts don't notify me at all no vibration no sound and no notification the only way to tell if I got a text is to actually open my phone and look at the text icon badge and if I have a 1 or more I have a text it's very annoying and it did it out of no where if anyone knows or has suggestions on how to fix this please give me some advice thanks!

I have spent over an hour trying to figure this out and I'm just lost ...... I know I can't be the only person to have this happen lol
