Someone stepped on my samsung galaxy tab S

It comes on but the end where you plug in the charger, where there are spider web cracks showing on the screen but you can't feel them, there is a black blotch and there are also lines running across the screen about every inch. I can't get any of the apps to open when I can get to that screen, other times it just shows a white screen. I've only had it 18 months...ugh! Is it even fixable? If not is there a way to get my stuff off of it i.e.pictures, videos and documents?
