Android 9 Pie vs Android 8.0 Oreo Walkthrough: What’s New

Redesigned (Colorful) Settings Menu

As expected, Google changed the settings menu again this year. 

The settings menu, layout, and options are all relatively the same as we got with Android 8.0 Oreo. However, they're colorful and easier to see or access. The buttons for specific setting options are rounded on the edges too, instead of square boxes to select stuff. 

Some things like WiFi preferences were slightly rearranged, but for the most part, everything is the same. Only with some added colors. This is a nice change from stock Android Oreo, which looks somewhat boring. However, some think this looks too much like Samsung's TouchWiz user interface.
