Some units of HTC HD2 were shipped with camera problem in which a pink hue spot was noticed in the center of all the snaps taken from the 5 megapixel autofocus camera on board HTC HD2. HTC first confirmed it as an hardware issue but then later they found out that it was infact a software issue, rather than a hardware one. And now HTC has rolled out a software update which fixes this problem on all the defected handsets.
