[Q] Strange Screen Colouring Since Update

view story

http://forum.xda-developers.com – I've had my S4 for nearly 2 weeks, yesterday I got an update, no updates were available when I checked last week but it decided to tell me there was one yesterday, so I updated and since then on black screens (Mostly Messaging & Setting Menu's) I'm getting a strange colour banding, on the right hand side the black has a slight lighter greeny tint, tho it's not there if I look at a black wallpaper and also goes away if I change the screen mode to Dynamic, all the other settings and Adapt display it is visible, most noticeable at night tho, I'm sure it wasn't there before the update, Anyone (HowTos)
