I just noticed this yesterday. When I breathed on my phone to wipe it with a glass cleaning cloth, I noticed a lot of matte-looking spots on the screen when holding it to the light so it reflects it into my face. Reminded me of mold at first (how it grows in spots on bread). I tried wiping it over and over by breathing on the glass, but they're still there. As soon as the glass dries up from the breath's moisture, the spots aren't visible anymore, and the back plate goes back to being glossy. Anyone else have this? The entire thing is in spots, and they're not in any particular pattern. The front of the phone looks normal, and I don't want to use Windex on the back because I don't know how the phone would react to it.
