Sansa Clip Sport Plus Corrupted Graphics

I have been using my Clip Sport Plus for about a month. I was walking and jamming to some U2, and some Thrice, when I dropped on the concrete. The screen cracked, and the graphic turned black all around where it cracked. It has now spread to cover approximately 90% of the screen, and is still spreading.

I have two questions: One, is there a warranty? And two, is there anything I can do about it?

that is not a corrupted graphic. That is a broken screen. No physical damage is not covered by the warranty.
