Over the weekend, Alex Dobie, Executive Editor of Android Central, posted this tweet, showing what appears to be screen burn-in on his Google Pixel 2 XL review unit.

From this Android Central post:

Viewing a grey image on the screen, you get a clear look at where the navigation bar has started to settle in on the display. You also interestingly see the portions of pixels where the back, home, and recents buttons go — those don’t seem to be burned in themselves (displaying white instead of black), but the outlines clearly show where they are compared to the black portion that’s burned in. Or that may be some optical trickery and the buttons are burned in. We’re just not sure what we’re seeing here.

Deiter Bohn, Executive Editor of The Verge, following with this article, reports that he is seeing similar burn-in on his review unit, and:

Screen burn-in isn’t an uncommon issue, but it does seem especially worrisome that it’s showing up within a week or so of these units coming into usage. It’s also possible that what we’re looking at here is image retention instead of actual screen burn-in. If that’s the case, then it’s not as permanent. Neither one is good, but “ghosting” goes away where burn-in may not.

From Google:

We put all of our products through extensive quality testing before launch and in the manufacturing of every unit. We are actively investigating this report.

Hopefully for Google, this will turn out to be fixable.
