iPhone 4 camera blurry with flash

After I accidentally broke the back of my iPhone for by dropping it I finally took it to the Apple store and got the back plate replaced. Now about 8 hours later I wanted to take a video of my friends and turned the flash on but the whole screen was white and blurry. I took my a microfiber cloth and cleaned the lens on the outside and it still doesnt help. What should I do now? By the way the Apple store is about 2 hours away.
