Nokia has been facing a lot of criticism for nearly all of their moves including the highly debatable and the much controversial Nokia-Microsoft deal. Irrespective of all this, there is no denying of the fact that the latest Symbian (former Symbian^3) handsets from Nokia have been selling in decent numbers.
The Finnish giant managed to sell nearly 4 million N8′s in the last quarter of 2010 and the C7 is also selling in decent quantities. Both these handsets the N8 and the C7 use an AMOLED screen, with the latter featuring a CBD (ClearBlack Display) as well. Now, some N8 and C7 owners are reporting that the screen on their handset(s ) is having some red-purple color tint and poor color gradients issue.
Apparently, the issue is a hardware one and not a software one or a poor color calibration of the screen from Nokia. The issue is not a widespread one but quite a sizeable number of N8/C7 owners are facing the same problem.
Nokia has not made any official statement regarding this issue until now, and if the issue is a hardware one, I doubt that they will!
