The way I figure it is I don't mind the blue tint off-angle because... well, I don't go to the effort to look at my phone at a weird angle. Screen burn-in, though, that's a concern.
Good news is, for those of us who have already (or do in the near future) received ones that exhibit these, if they make a change for future production to correct for it, it's a tacit admission of a flaw with the early units, and clear grounds for a warranty exchange.
Haha, apparently a lot of people like to look at their phones with all kinds of weird angles. Been using my 2 XL since last Thursday. Yes it does have a blue tint, but I haven't really noticed it. Why? Because I look at my phone straight on.
Then you're some of the lucky ones who got a decent screen. What SO many people are missing on this issue is that there is huge variability with the blue tint. Some aren't too bad, others are really horrible. People need to stop assuming that since their phone is ok, everyone else is complaining too much.
Hopefully the blue tint was only an issue with the early phones and really is being addressed, as the reps said. But being that it's clearly a hardware issue, I'm not sure if it could be addressed that quickly. I guess we need to wait and see if the issue clears up as more phones get to users.
