There are two words that when seen in print by a smartphone user, will instantly get him or her to react by installing a particular app, or checking to see if an update has been received for an app already installed. Those two words are Dark Mode. This is a feature that reverses the typical black text on white background so that the screen shows white text on a black background.

Android Q is supposed to feature a system-wide Dark Mode in its final version, and iOS 13 is rumored to have the same thing. Google added the feature over the last year to a number of core Android apps that it updated to the retina melting Material Design. The latter features plenty of bright white in the background. Dark Mode, as we’ve just insinuated, helps protect users from a blinding white background that is intensified at night or in dark rooms. It also can save some battery life on phones with OLED screens since more black in the background means fewer energy consuming pixels need to be turned on. And many feel it just is a different and “cool” look.

Besides Dark Mode, the new beta update adds the name of an audio file to the bar found on the display that includes the play button.
