Android Central's Alex Dobie shared a photo on Twitter on early Sunday that shows faint outlines of Android's navigation buttons at the bottom of the display. 9to5Google, The Verge, and Ars Technica also experienced the issue.
That's some pretty wild OLED burn-in on the Pixel 2 XL after maybe 7 days of full-time use pic.twitter.com/EPJTs6D0Kg— Alex Dobie (@alexdobie) October 22, 2017
In a statement to The Verge, Google said it is "actively investigating" the reports.
The Pixel 2 XL screen has been designed with an advanced POLED technology, including QHD+ resolution, wide color gamut, and high contrast ratio for natural and beautiful colors and renderings. 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.Google hasn't confirmed how many users are currently affected.
Google sourced the Pixel 2 XL's plastic OLED display from LG, which could be the root of the problem, given that the smaller Pixel 2 and original Pixel's Samsung-supplied OLED displays have experienced far fewer issues.
Apple is also sourcing OLED displays exclusively from Samsung, so if the issue stems from LG, then the iPhone X shouldn't be affected either.
LG's own V30 smartphone has suffered from many of the same display issues, which has also included banding and uneven colors.
Screen burn-in is typically a result of static images or on-screen elements displaying on the screen uninterrupted for a prolonged period of time. The issue can result in persistent discoloration or a "ghosting" effect on the screen.
