Extensive testing of the Pixel 2 XL display show that its decay characteristics are comparable to OLED panels used in other premium smartphones. The differential aging should not affect the user experience of the phone, as it’s not visible under normal use of your Pixel 2 XL. We understand, however, that it can be concerning to see evidence of aging when using a specialized display test app, so we've taken steps to reduce differential aging through software.
We’re currently testing a software update that further enhances protections against this issue by adding a new fade-out of the navigation bar buttons at the bottom of the Pixel screen after a short period of inactivity. In addition, we're working with more apps to use a light navigation bar to match their app's color scheme. The update will also reduce the maximum brightness of the Pixel 2 XL by a virtually imperceptible 50 cd/m2 (nits), thereby significantly reducing load on the screen with an almost undetectable change in the observed brightness.
