One of the most notable changes in iOS 18 beta 3 is the automatic application of dark mode to Home Screen app icons. Previously, only Apple’s first-party icons received this treatment, but the latest beta extends this feature to third-party apps with simple color palettes. This algorithmic approach ensures a more uniform look, especially for fans of dark mode who have long customized their iPhone Home Screens for a consistent aesthetic.

While this change is a welcome addition for many, it comes with caveats. The automatic dark mode treatment works best on icons with single glyphs or letters like Facebook and Uber. However, more complex icons might display white or gray pixels at the edges, creating a less polished appearance. Apps that already use black icons remain unaffected.

iOS 18 beta 3 also introduces dynamic wallpapers that change color throughout the day, adding a touch of personalization to your iPhone. The flashlight interface has been refined for iPhone 15 Pro and Pro Max users, and the Photos app’s “Select” button is now always visible for easier navigation.
