I have only had my radio for two weeks now and have the same trouble. Some dust has got under the display screen. Of course Uniden did not desing a seal so this would not happen. My MOTO does the same thing, but it takes about a year for some dust to get under it. O well just open up the back from time to time and clean it out with a can of air duster so I don't scratch the bottom surface. That would not be good. I guess when you tend to take a portable wherever you go its going to happen. Dust is everywhere
