I'm not exactly sure what your second sentence is supposed to say, SmileyBourne, but the wallpaper and lock screen have very little if anything to do with this issue. The only way they would matter is if you only turned your phone on to the lock screen or home screen over and over and over and just left them on that screen for hours and hours at a time. Maybe then it would matter if those screens were never changed. And if that's what someone did, they might have the actual image on their home/lock screens burned in to the screen, but that isn't what is going on here. This phone is experiencing a color shift over the entire screen area MINUS the area of the status bar. So, basically every time I use my phone for browsing, news, some games, phone calls etc., the usage contributes to the problem. I still don't know whether or not they will fix it as I am working out the replacement phone issue for while mine is gone, but when I do, I'll update this thread.
