After having my new pixel 2 XL for less than 24 hours, I saw some banding and a blob on the side of the screen. I'll attach a photo if it works. I contacted a Google support which had me try a few things. But then they told me I should try the retailer first. I haven't had a chance to go back to the store yet. But now it seems the issue may have gone away. Has this happened to anybody else? The line and blob were pretty visible at first but now I can't really see them. I'll attach what they look like when I've first notice the problem.
Should I still try to get a new phone? Or was it something weird since it was brand new and that'll never see it again?
