I know Makubex1980 said it's a hardware problem but I think maybe they can't fix the problem but they could make it better with software
Considering W10M released for Lumia 930 couple weeks ago I want to know anybody installed? Any Change??
Thanks
if its flickering, get it fixed, probably under warranty.
As for purple tint, you may be able to fix, or at least compensate for it using the Color Profile options under the Display settings.
Windows 10 has not been released for any phone officially nor is it ready for any phone.
An early-access program is what you're thinking of, and is not recommended for normal users. Many things are broken and it can't fix hardware problems. It doesn't include firmware either.
