Feature flags are options that can be enabled or disabled that alter how the Device's operating system and apps function. Although Android introduced feature flags with Google Chrome, it wasn't until the release of Pie that the options expanded beyond the browser. The Feature flags accessible in Android 9 mostly change how the user interface appears.
