We've been following Android 12's new screen-dimming feature for some time — not because it's that revolutionary, but because Google keeps changing the name for it. We've gone through "Reduce Bright Colors" and "Reduce Brightness," but as of DP3, Google appears to have settled on a less easily understandable "extra dim" name.
Although the feature has gone through a few different names since it debuted in DP1, it works simply. Extra dim is a new quick settings toggle that reduces screen brightness to a configurable level separately from the brightness slider itself, which does not change. Long-pressing the toggle (or navigating to Settings -> Accessibility -> Extra dim) pulls up a simple settings menu for how it works.
