iOS 10 offers about 40 top-level categories in its Settings app and seemingly innumerable options in those categories. How can you find a little-used setting, particularly since Apple sometimes moves things between categories during major iOS releases? The solution is the Settings app’s hidden Search field. To reveal it, pull down on the main settings screen (iPhone) or left sidebar (iPad). Tap the Search field, enter text describing the setting you want to find (try typing Fa to find Facebook, FaceTime, and Safari Favorites), and the results appear immediately. Tap a result to jump to it, but also notice that each result shows a path, so you can find that setting manually in the future.
