The Home screen, which we discuss in Chapter 1, isn’t the only screenful of icons on your phone. After you start adding apps from the App Store (see Chapter 15), you’ll likely have multiple screens.

Initially, you see three tiny dots above the Phone, Safari, Messages, and Music icons. Each dot denotes an additional screen, containing up to 20 additional icons on the original iPhone SE, and up to 24 on the iPhone 6 and later. The icons can represent apps, folders of apps, or (as you’ll learn later in this chapter) widgets. The middle dot, which is all white, represents the Home screen, or the screen you’re currently viewing. The next dot to the right, in gray, is the first additional screen on which you can park icons. You get to it by flicking right to left (assuming you’re on the first screen). You can have 15 screens in all; as you add screens, you add dots.

If you flick all the way right to left, you get to the today screen, which used to be part of Notification Center but is now out on its own. Flicking all the way to the right takes you to the new App Library, which we also get to later in this chapter.

The four icons in the bottom row — Phone, Safari, Messages, and Music — are in a part of the screen known as the dock. When you switch from screen to screen as just described, these icons remain on the screen, that is, unless the Today screen or Notification Center is in view or you’re inside an app.

You can easily move icons within a screen or from screen to screen. Gently press and hold down on any icon for a moment until a menu appears. Tap Edit Home Screen on this menu and all the icons on the screen will begin to jiggle. Then drag the icon you want to park elsewhere to its new location. The other icons on the screen kindly step aside to make room. To move an icon to a new screen, drag it to the right or left edge of the screen. When you’re satisfied with the new layout, press the Home button on compatible models or Done on models without the button to stop the jiggling.

An X also appears on each of the jiggling apps. Tap the X if you want to remove the app from your phone. You’ll get one last chance to change your mind.

In case you're wondering, the menu where you found the Edit Home Screen option offers choices specific to the given app. For example, Apple’s Keynote presentation app has options to create a new presentation or to start with an outline.

Want to jump back to the last Home screen of icons you had open? Simply press the Home button on models that have one, or swipe up on models that’s don’t. Want to jump to the first screenful of icons, assuming you’re not already there? Press Home or swipe up again.

Press and hold down the Home key for more than a second or so to summon Siri (unless you turn the Siri feature off in Settings).

On the iPhone X and later models, press and hold down the side key for more than a second to call Siri into action.
