My dad recently spazzed and threw my psp really hard on the floor, nothing really happened other then a few cracks here and there. But the faceplate on the top right where the R button is, has more room, so you can see a little inside the psp. Today I noticed there was dust behind the screen, and it's really annoying. Can't really notice it most of the time, but will this be a problem later on? Could it damage the psp in anyway? If there's something I can do to make it better, please let me know.
