Buttons on my IPhone 4s aren't working?

All the buttons including my home, lock, volume, and mute aren't working. I can physically press them but nothing happens, I'm stuck looking at messages, Please Help!

Hold down the power and home buttons at the same time see if there's any response. One button me point to a hardware failure but all three I do not expect that to happen. I also would advise perhaps restoring the phone and see if that helps at all. If it doesn't it's probably the phone itself and will have to be serviced.

You're phone is probably done if all the buttons are broken
