If your screen has the pink tint issue look on your box and see where it was manufactured. Post it here so we can see if there is a connection between the two.
I'm not sure about the pink thing. Are you talking about when looked at from an angle? If so, then yes I see a slight pink tint to it when I face the top of the phone away from me. I'm not sure if that is because of the phone or because of the screen protector. When I look at it straight on there is not tint.
Mine is VZW from Vietnam, but the screen is beautiful. White is whiter than the LG G6 sitting next to it or the previous S7 Edge. Has anyone seen the "update" come through that is supposed to allow calibration? I find it hard to believe that will just magically get through the carriers in a day.
