IPhone vibrates before I get text?

When I receive a text message on my iPhone 4S, my phone vibrates around 5 seconds before my phone sends me the alert that I have a message. Usually this happens at the same time. How do I fix this?

Uhm, as long as the phone isn't broken, then you shouldn't have a problem. I don't know why you're so worried.

There's no way to fix this its just your phone receiving the message when it buzzes but it might not show in the lock/ home screen for a couple seconds
