A system-wide dark mode allows users to enable a light-on-dark color scheme for the entire iOS and iPadOS user interface, all native applications, and supported third-party apps. It can be manually turned on or set to automatically switch between light and dark modes based on the time of day. iOS 13 introduces an updated volume indicator that appears on the left side of the screen and allows the user to set the volume by sliding a finger on the indicator. Previous versions have the indicator in the center of the screen.
