Software updates can be quite boring, with security patches, bug fixes, and little else. Android 12 is not one of them. Perhaps the biggest single design change in the OS's history, it ushers in a language Google is calling "Material You" and will be using across all its apps, web services, etc. in the future. "Fun" is perhaps the best way to describe it, with oversized buttons that change colors to match the wallpaper, bubbly animations, and a revamped widget system that will hopefully encourage developers to redo their aging offerings. As is traditional for Android, it will arrive on Google's Pixel phones first, and a public beta is available now.
