Double tap does what, and why you might want to stop it
On iPhones, double tap is a shortcut that activates when you tap the back of your phone twice in quick succession. By default, it opens your app switcher or takes a screenshot, depending on your iOS version and settings. If you use an external keyboard or mouse, or if you rest your phone against something while working, accidental double taps can interrupt your focus or trigger actions you didn't intend.
The feature exists to give you a quick way to switch between apps without reaching the top of the screen. But if you find yourself triggering it by accident — especially if you're typing on a separate keyboard and your phone is propped up nearby — turning it off is straightforward and takes less than a minute.
Key Takeaways
- Double tap on the back of your iPhone is controlled in Settings under Accessibility, not in a general gestures menu.
- You can turn off double tap entirely, or change what it does — for example, set it to open Siri or Control Center instead of the app switcher.
- The setting is called "Back Tap" and appears only on iPhone 11 and newer models.
- Turning off back tap does not affect any other iPhone gestures or keyboard shortcuts.
Where to find the back tap setting
Open the Settings app on your iPhone. Scroll down and tap Accessibility, then scroll down again and look for Back Tap. This option only appears on iPhone 11, iPhone 12, iPhone 13, iPhone 14, iPhone 15, and newer models. If you have an older iPhone, this feature is not available on your device.
Once you tap Back Tap, you will see two options: Double Tap and Triple Tap. Each one can be set to a different action, or turned off entirely. Tap on Double Tap to change or disable it.
How to turn off double tap completely
In the Double Tap menu, you will see a list of actions: App Switcher, Screenshot, Siri, Spotlight, Accessibility Shortcut, and others depending on your iOS version. At the very top of the list is None. Tap None to disable double tap entirely. Your phone will no longer respond to taps on the back.
Once you select None, the setting saves automatically. You can test it by tapping the back of your phone twice — nothing should happen. If you change your mind later, you can return to this same menu and choose a different action, or select None again.
What to do if you want double tap to do something else
Instead of turning off double tap, you can reassign it to an action that is less likely to interrupt your work. For example, if you rarely use Siri voice commands, you could set double tap to open Siri instead of the app switcher. That way, if you accidentally tap the back of your phone, it will just set up Siri — which you can dismiss by tapping elsewhere or saying "cancel."
To change what double tap does, go back to Settings > Accessibility > Back Tap > Double Tap, and choose a different action from the list. Screenshot is another common choice if you take frequent screenshots and want a faster way to capture them. Spotlight opens the search screen, which is also straightforward to dismiss if triggered by accident.
Why back tap might set up when you don't expect it
Double tap triggers when your finger makes contact with the back of the phone and lifts away twice in quick succession. If your iPhone is resting against a desk, table, or keyboard stand, vibrations from typing on a nearby keyboard can sometimes cause the phone to register a tap. This is especially common if you are using a mechanical keyboard or if your phone is on a hard surface.
If you find that double tap keeps activating even after you have set it to None, check whether your phone is touching something that vibrates. Moving your phone further away from your keyboard, or placing it on a softer surface like a mousepad or cloth, usually solves the problem. You can also use a phone stand that holds the device at an angle, away from the desk surface.
How back tap interacts with external keyboards and mice
Back tap is a hardware feature of the iPhone itself and does not depend on whether you are using an external keyboard, mouse, or trackpad. Turning off back tap will not affect any keyboard shortcuts or mouse gestures you have set up. Your external input devices will continue to work exactly as before.
If you use an external keyboard with your iPhone, you may also want to check your keyboard settings in Accessibility to make sure no other gestures are set to trigger by accident. But back tap is separate from those settings and can be managed independently.
Frequently Asked Questions
Does turning off back tap affect anything else on my iPhone?
No. Back tap is a single feature controlled in one place. Disabling it does not change any other gestures, shortcuts, or accessibility settings. Your phone will work exactly as it did before, except that tapping the back of your device will no longer trigger an action.
Can I set double tap and triple tap to different actions?
Yes. In the Back Tap menu, you can set Double Tap to one action and Triple Tap to another. For example, you could set double tap to None and triple tap to Screenshot, so only the triple tap does anything. This gives you more control over what triggers by accident.
What if my iPhone doesn't have a Back Tap option?
Back Tap is only available on iPhone 11 and newer. If you have an iPhone 10 or earlier, this feature does not exist on your device. You can still use other accessibility settings to customize how your phone responds to gestures, but back tap specifically is not an option.
Will disabling back tap slow down my iPhone or use more battery?
No. Back tap is a straightforward software feature that has no impact on performance or battery life. Turning it off or on makes no difference to how fast your phone runs or how long your battery lasts.
