It's hard to tell how many of these "issues" are being blown completely out of proportion to generate clicks/view for these tech sites and reviewers.It's hard to tell how serious many of the claims are vs. this is a flagship phone that costs a boatload of money and it should be flawless.
It's not like Apple and Samsung haven't had major press flare ups with their product launches. Some of the other OEMs get away with things because not enough people notice.
I'm still in the camp of people that are disappointed they cancelled the "middle" Pixel phone that was supposed to be mostly bezel-less like the XL2, but slightly smaller. IMO, they could have killed off the other two if they did that one right.
