It’s old news, but I still want to note these friends who are going to buy the Nokia Lumia 900 from AT&T, previously there some users reflected that the Lumia 900 ‘s screen become purple sometime, and recently Nokia confirmed the existence of the problem on its official Twitter, Nokia said that they will release a software update to fix this issue as soon as possible.
As for when Nokia will release the update for Lumia 900, currently it is still unknown, but why the Nokia Lumia 900′s display would appear purple, it is likely because of the Lumia 900 screen calibration failure.
