I received the screen twice now and both times complained. Reason is that the white fabric was discolored times each gray. I phoned this regard with Walser. The first time it was said that the error was known. But he only appears in less than one percent. In the second call, it was then that the error is not known. Strange.
With me were definitely two of two flawed.
Amazon has certainly the article for the time being decided to take from the program and to examine the case.
