Hello,
my VP2 also came back from HTC Romania with no word about this hardware failure.
I had an agreement with the htc support for full refund, but they returned it nevertheless.
I have also send the 2 pictures below to the support, to show the failure. These are two frames of a handy video. It´s difficult to make a picture of this failure, so thefailure is only seen in the middle of the picture, when you zoom in. The left and right side of the pictures are to blurry to show the failure, but it is noticeable on the whole screen, with my own eyes.
