You’ll use many different apps throughout your day. Finding and launching apps using Home screens can be cumbersome and slow when you have a lot of apps installed. You can easily view and switch between your recent apps with a simple gesture.
The Recent apps screen displays recent apps as a series of “cards” or thumbnails of the screens. Depending on your phone manufacturer, it may display the open apps on top of one another or side-by-side (as shown here). Drag a finger to scroll through the apps and tap on an app to open.
You’ll also notice a Screenshot button and a Select button at the bottom of the screen.
