How to navigate iPhone X
> Power off
Now that holding the side button — the new name for the sleep/wake button — invokes Siri, you can power off in two ways: Go to Settings > General > Shut Down; or hold either of the volume keys in addition to the side button for a few seconds to get options for powering off, Emergency SOS, and Medical ID. The shortcut for Emergency SOS is five quick presses of the side button.
> Tap to wake
If Settings > Display & Brightness > Raise to Wake is on, raising your iPhone will wake its screen. But you don’t have to do that, or press a button, to see the Lock screen, just tap the screen. Depending on Settings > Notifications > Show Previews, and iPhone X’s view of your face, you might need to pick it up to read notifications — a good reason to add an iPhone dock to your desk.
To take a screenshot, quickly press and release the side button and either volume button. iOS 11 briefly displays the shot at the bottom left of the screen; tap that to open the Instant Markup tool, where you can annotate the screen, share it, or delete it if you don’t also want to save it to Photos. If you ignore the preview, the screenshot will be saved to Photos automatically.
Lock screen shortcuts
The Lock screen includes shortcuts to the flashlight and camera features, which saves you opening Control Center or swiping left for these. To avoid accidental activation, these buttons require you to press firmly.
To invoke accessibility features, quickly press the side button (formerly called the sleep/wake button) three times. What you get depends on your choices in Settings > General > Accessibility and the Accessibility Shortcut item at the foot of that page.
Call upon Siri
Many functions that used to use the Home button now use the side button on iPhone X. To call upon Siri, you can still say “Hey Siri,” but if it doesn’t respond, speaking is inappropriate, or you prefer to use the Type to Siri accessibility setting, simply hold the side button for a moment.
Apple Pa y
To make a payment using a bank card you’ve added to the Wallet app, double-click the side button. Note that because opening the app switcher on iPhone X uses an on-screen gesture, you can call upon Apple Pay while in an app, rather than having to open Wallet as you did on previous iPhones.
Force a restart
With luck, your iPhone X will never act up to the point of requiring you to force it to restart. If it does, though, press and release the volume up button, repeat for the volume down button, then hold the side button until you see theA pple logo.
