pixilated camera

I have a case for my z10. It's Verizon and I got it a week ago...today I dropped it with the case and the camera would not open up. It's showed black and some pixilated pink on the bottom. But then it worked again. Not sure why it die that, I was afraid it broke or something. I still have the 2 weeks to exchange for another. Should I do it or was it just a random glitch on the phones part...i don't want to own a broken phone that's damaged when I have an opportunity to return it




Ps. Do a holes telling me to search for it because I did. I typed it pink camera, z10 camera not working and what not. Please help if you know. Thanks
