Purple display issue on Lumia 930
Do you have a Lumia 930? If so, you might want to make sure that your phone's display does not have a purple tint to it, as a small number of users are reporting the issue seen in the picture above.
The issue is quite simple: a small number of Nokia Lumia 930 phones have a purple hue to the display Fortunately, this is not a hardware defect and can be adjusted using the built-in display calibration tools. If you find that your phone has a purple hue to it, here's how you can fix it.
To fix the color issue, open the Display setting and head over Settings >Display >Adjust Color. When you're in there, just set the Tint option from neutral to green. After doing this, your phone's display should be as good as new.
That's about all there is to this issue, and aside from minor purple display problems, the 930 looks to be another solid phone out of the gate. While we don't have a final verdict on it yet, as our review is still in progress, we have previously reviewed the Lumia Icon, which is quite similar to this device.
