The screen on Google's Pixel 2 XL is taking a hammering. First, users noticed how its weird colour-shift effect made it look excessively blue when viewed off axis. Then, they saw how the device's default settings can make images look dull and dreary. But the latest issue with the Pixel 2 XL's POLED screen may be the worst yet. After only about a week, several users have reported seeing the effects of screen burn-in on Google's latest high-end phone.
