A true system-wide dark mode is shaping up to be one of the most anticipated early elements of Google's upcoming Android Q release — and little by little, apps appear to be gearing up to support the new setup.According to a leaked early development build of the software, Android Q will provide a single switch that shifts an entire device into a darker state — not only elements of the operating system but also the interfaces of individual apps.

A since-deleted posting by a Googler had previously suggested that dark mode was an "approved Q feature" and that the teams responsible for preloaded Google apps were told to make sure their programs had compatible themes ready to roll by the time Q arrived.
