My iPhone 6 status bar randomly fades to a purplish color

Hello! My iPhone 6 running ios 8.0.2 is randomly fading the status bar to a purplish color as you can see in the picture, i havent found similar complaints and im not sure if its a software or hardware issue, ive tried resetting the iphone it goes back to white but starts randomly fading again, do any of you has the same issue? what should i do?

Thanks!
