Google continues to deploy dark modes for its applications, probably in preparation to match its upcoming night theme in the OS. Once the messages, contacts, calculator and update updated, the company now focuses on the schedule so that users can benefit from a more user-friendly interface, save battery and look more enjoyable, at least for some people, to manage their schedule.

Although the new mode requires the update of the application to the latest version, the application is gradually extended to users via a server-side switch. However, the feature should be available to all users by the end of the month. Once you are eligible, you can manually activate the dark mode by going to Settings -> General -> Theme. If you already use Android Q and have activated the night theme for the entire system, the application will switch it automatically.
