Switch Between Light and Dark
The flagship feature of iOS 13 is undoubtedly Dark Mode. Now, you don’t have to settle for the typical light UI design on your iPhone. Just pop over to the Control Center and switch on Dark Mode for a systemwide switch to the dark side.
Dark Mode changes pretty much every facet of iOS, making it a good choice for nighttime reading. Better yet, most third-party apps are compatible with Dark Mode these days and will automatically switch according to your current setting.
