People with the Google Pixel 2 XL review units earlier reported few problems in its display like grainy textures in low light and muddy colors. But now the devices face another big problem and this time it’s screen burn-in.

The issue was first reported on Twitter by Android Central’s Alex Dobie. It is clearly noticeable that when you look at the screen with a gray background, you see faint outlines of the phone’s navigation buttons on the bottom.

After Alex reported the issue, Dieter Bohn at The Verge also confirmed seeing something similar on his own review unit.

Screen burn-ins aren’t uncommon, but it does seem worrisome that it’s showing up within a week usage. It’s also possible the issue is the image retention instead of screen burn-in. But in both cases, neither one is good.

Android Central reached out to Google with their concerns, and a spokesperson replied with the following statement:

“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.”
