My iphone 5 turns black all the time and i can't get it to work for 2 minutes?

I try clicking everything and it just won't turn on. Like i might have just left it alone for 30 seconds and i can't get the screen to turn on.
I thought iphone 5s were meant to be better than the rest…

Go to the Apple store. They will be able to fix it for you. The price for fixing though, either free for a manufacturing defect (likely that the screen or buttons aren't connect properly) or $100 if the screen is faulty (and they """know""" you damaged the phone).

You can try restoring it using the computer where you last sync it. Use itunes to restore it. If it does not work then you have to do something else.

If it's still under warranty the it would be best if you make an appoint to an Apple store to have it checked because if you are going to let others open it, it will void your warranty for sure.
