How to Use iPhone Action Button to Customize Functions

To swipe between iPhone apps with gestures, use the bottom edge of the screen on Face ID models. Swipe left or right along the Home indicator to move to the previous or next open app. For a full app switcher gesture, swipe up from the bottom and pause in the middle of the screen.

Steps

Unlock the iPhone and open any app. App switching gestures work best when at least two apps are already open.
Place a finger on the Home indicator at the bottom edge. On some screens, the gesture still works even if the indicator is hidden.
Swipe left or right along the bottom edge. The iPhone moves directly to another recent app.
Swipe up from the bottom and pause for a moment to open the app switcher gesture view. Swipe sideways through open apps, then tap one to open it.
On iPhones with a Home button, double-press the Home button instead. Side-swipe app gestures are mainly for models without a Home button.

Common Issues and Fixes

Gesture does not switch apps: likely cause is only one app being open; fix by opening a second app first, then try the swipe between apps gesture again.
App switcher does not appear: likely cause is swiping too fast upward; fix by swiping up slowly and pausing briefly in the center of the screen.
Side swipe opens app content instead: likely cause is starting too high on the display; fix by starting the iPhone gestures from the very bottom edge.
Gesture feels inconsistent in games or full-screen video: likely cause is app-level gesture handling; fix by swiping once to reveal the Home indicator, then repeat the gesture.
Older iPhone does not support the same motion: likely cause is a Home button model; fix by using the Home button app switcher instead of the app switcher gesture.

Quick Tips

Landscape mode can make the swipe between apps gesture feel less precise. Returning to portrait mode often improves accuracy.
Recently closed apps do not appear in the app switcher. Only currently open or suspended apps can be reached.
Guided Access, accessibility settings, or temporary system lag can affect iPhone gestures. Restarting the device may restore normal behavior.
A case with a thick bottom lip can interfere with edge swipes. Testing without the case can confirm the cause.

Can app switching gestures be turned off on iPhone?

Standard iPhone gestures for app switching cannot be fully disabled on Face ID models. Some apps may temporarily change gesture behavior in full-screen mode.

Is swiping between apps the same as opening the app switcher?

No. A bottom-edge left or right swipe jumps directly between recent apps, while the app switcher gesture shows all open apps in a card view for manual selection.
