How do you fix your Samsung Rogue when the slide part is stuck?

I was taking my old case off of my Samsung Rogue and I heard a crack. The case broke a bit and I think part of it got stuck in the sliding part of the phone. My phone works, but it doesn't close all the way. Is there any way to fix it?|||If there is foreign matter stuck in the slider, opening and closing the slider might shake it out. If not, the crack you heard could be the slider itself. If thats the case you would probably have to get a new phone unless you put up with the phone the way it is.
