Swipe to Switch Apps
You can switch between apps by swiping your finger right or left across the Home Indicator. This lets you move quickly (and conveniently) to the app you were using.
To See Multitasking Controls
If you swipe up from the Home Indicator you will be taken to Home but if you do it a little more slowly, the iPhone’s Multitasking will come up. In this view you will see previews of the recently used apps. To use any one of them, just tap on it.
You can bring this view up even more quickly if you want; just swipe up from the bottom left diagonally.
Customize Control Center
The Control Center lets you access some of your iPhone’s features without necessarily launching an app. If you have a phone in the iPhone X series, place your finger at the top right side of the screen and swipe down to access the Control Center. If you swipe from any other side of the top of the display, you will open the Notification Center.
The Control Center is much more fun than you think. You can customize it. Launch the Settings app and select Control Center then go to Customize Controls. On the screen that will appear, you can add whatever buttons you want.
Invert Bright Apps
The Smart Invert Colors is an Accessibility feature that can help with bright white pages. It inverts the display making black white and white black. This feature is smart because it will not invert media items such as photos. It is very helpful when you are using your phone in the dark. To enable it, go to Settings > General > Accessibility then check Smart Invert Colors.
Fast Access to Flashlight or Camera
iPhone X phones have two icons at the bottom of their lock screen; a camera to the right and a flashlight to the left. These two icons are very important. However, tapping them will not do anything and to trigger them you must use 3-D touch (touch and hold).
Viewing the Today Screen
The Today Screen is found on the left side of the Notification Center. It contains widgets which sometimes have useful information. To see this screen, swipe down from the top of the screen (just not from the top right) to bring up the Notification Center. Then swipe to the right to see the Today view.
Unsubscribing from Notifications
In iOS 12, notifications can be managed from the Notification Center. Swipe left on a notification to bring up a sub-menu. Here you can tap on Manage, Erase All or View.
Go to Settings then Siri & Search. In the screen that will come up, you will see a Suggested Shortcuts list. Tap on whichever one you think will make a useful shortcut, record a key phrase and you have yourself a new Siri command.
Go to the Top with One Tap
If you have been scrolling down a list for a while and want to go back to the top, you do not need to scroll back up. Tap the menu bar or the top of the app you are using.
