iOS users are already benefiting from the feature since Monday in iOS 9.3, with Apple naming the new option Night Shift. Google is calling theirs "Night Mode."
Night Mode will be found in a somewhat hidden settings menu called "System UI Tuner," and can be turned on and off manually or set to operate automatically depending on the time of day.
There's no word yet whether the feature is just an experiment or whether Google plans to incorporate it into its next operating system. — AFP Relaxnews
