So I'm still hearing mixed things about this issue - 2 weeks in with the phone here in the US.
The problem seems to be caused by some form of adhesive or coating between the glass and LCD panel that needs the display to heat up in order for the pink to go away.
Here is what I found from some searching online:
The Good:
It seems that there are permanent and temporary fixes to this problem.
Solution 1: Keep the phone on full brightness (manual mode) for as long as possible until the pink disappears when you lower the brightness to your desired setting. Some users have tried this for 2 weeks or less and found it to work.
Solution 2: Place the phone in direct sunlight or UV light until the problem dissipates.
Solution 3: Adjust the Color Profile settings - such as moving the Vivid colors to a colder setting
Solution 4: Just use the phone as normal until it goes away or your eyes adjust. Or you just decide to overlook it lol.
The Bad
There seems to be only a small population of people that are observing this - me included :'( . So that would mean that this is a manufacturer defect at the least and you would need to return/exchange for a new one. This would only be applicable if you don't want to try any of the solutions and if the solutions don't work.
Here are some of the links to the solutions:

Let me know what you guys think.
As for me, I'm currently trying all of the listed solutions for 1 week now and still not noticing any changes. I will continue for 2 more weeks before I throw in the towel and get a new one.
