The best Oreo tip I have seen so far is to stick a fork into the cream so that you don't accidentally drop your cookie into your milk. Computer World came up with some tips and tricks for using Android Oreo that are almost as good! They said, "Go into the Apps & Notifications section of your system settings, then select any app and tap "App notifications." If the app has proper Oreo-level notification support (Google Photos is a good example), you'll be able to select different categories of notifications for the app and then change their importance level."
