At some point, a little dirt accumulates in the envelope, at the edges, easy to lose weight, make with Spüli clean, dry and she was as good as new! the call quality is not affected, only the phone is a bit thicker, but that does not bother me ... that it is still quite !! (By the way already the second envelope of this kind that I buy, because the first two years (!) Then something dirty was at the corners. So I can only recommend !!
