Hello!
It is true that there has been a lot of negative press about the Pixel 2 XL of late. While I am not making excuses for Google, every phone manufacturer has a unique glip or glitch or even a problem here and there that causes it to make the news. We've seen it happen with Samsung, LG, Apple, and now I suppose it's Google's turn!
All that being said, there's a sociological phenomenon here that is fascinating but also a little annoying for potential buyers. People are more likely to post negative reviews/experiences/reports about products or establishments than they are to post praise reports; which makes the number of dissatisfied customers/defective devices seem to be much higher than it is in actuality. Are there defective products? Yes. Dissatisfied customers? For sure. But not on the grand scale that we think we see. Especially since people very often come to forum sites like these to look for help, which would mean they'd be posting about issues with their device.
I think it really all boils down to what you, yourself thinks. If you want the 2 XL, go for it! Test it out in the stores and see how it works and runs. If you like what you see, then that's great! Also, Google is offering a two-year warranty on their Pixel 2 devices, so you really can't go wrong with it. If something happens to it, you're covered!
If it helps, my friend got the 2 XL about three weeks ago and loves it! He says he sees a very minimal blue shift, but only at an extreme angle when he tilts the device a specific way. Do not worry! And, as always, keep us updated on what you decide!
