Today I received my second hand red Lumia 920. An awesome device, however there is a problem with the display.... it's way too orange/brown. The differences between the displays of my lumia 800/nexus 5 and this Lumia 920 are incredible. I have made a picture to show the differences. What can I do to solve this problem? Just buy a new display? Or is there a problem with the software? The Lumia 920 operates on wp 8.1 and the seller told to me it was a demo model.
I really hope someone can help me....

you should have checked this out before buying it.

Try doing a hard reset. If it doesn't help, try flashing it. If this too doesn't help, probably changing the screen may help.
But can't guarantee that changing the screen will help as this could be a problem on the main board too....

Good luck.
