I can replicate it every time at low brightness, all I have to do is swipe through photos and the black borders light up green straight away for a few seconds, also seeing it on black loading screens.
Wish apple would come out and say what the hell is going on, be nice to know if they're working on a fix for phones that are still affected, or if they'll have a recall program for units that are affected.
Don't want to try the apple store lottery since one person got a display replacement for the same issue, 3 days later green tint reappeared.
