How to Enable and Use Back Tap on iPhone (iOS 14)

Back Tap is a hidden accessibility feature in iOS 14 that lets you trigger actions by double-tapping or triple-tapping the back of your iPhone. You can use it to take screenshots, open Control Center, mute your phone, or run shortcuts—all without touching the screen. This guide walks you through enabling it and getting the most out of it.

What You’ll Need

• An iPhone running iOS 14 or later (the feature is available on iPhone 8 and newer).
• A compatible case—very thick cases may interfere with the tap detection.
• No other special tools or apps required.

Step-by-Step

1. Open the Settings app on your iPhone.
2. Scroll down and tap Accessibility.
3. Under the Physical and Motor section, tap Touch.
4. Scroll to the bottom and tap Back Tap.
5. You’ll see two options: Double Tap and Triple Tap. Tap either one.
6. Choose an action from the list. For example, select Screen Capture to take a screenshot, or Control Center to open the control panel. You can also scroll down to Shortcuts to run a custom shortcut you’ve created in the Shortcuts app.
7. After selecting an action, you can immediately test it by tapping the back of your iPhone. The action should trigger.
8. Repeat steps 5–6 for the other tap option if you want both a double-tap and triple-tap action.
9. To disable Back Tap, go back to Back Tap and select None for each tap option.

Common Mistakes

• Tapping too softly: The back of the iPhone needs a firm tap, not a gentle touch. Use a quick, deliberate tap with your finger.
• Using a thick case: Some heavy-duty or thick cases can dampen the tap detection. If it’s not working, try without the case first.
• Confusing double and triple taps: Make sure you’re tapping the correct number of times. Double tap is two quick taps; triple tap is three. If you’re accidentally triggering the wrong one, slow down slightly.
• Not saving your selection: After choosing an action, you must tap the back of the phone to test it. If it doesn’t work, go back and re-select the action—sometimes the selection doesn’t register if you don’t tap the back to confirm.

Tips

• Use different actions for double and triple taps: For example, double tap for screenshot, triple tap for Control Center. This gives you two quick shortcuts.
• Pair with Shortcuts: Create a shortcut that performs a series of actions (like turning on Low Power Mode and enabling Do Not Disturb) and assign it to a back tap.
• Test with a case on: If you use a case, test Back Tap with it on. Some thin cases work fine, but you may need to tap a bit harder.
• Adjust tap speed: If you find the taps aren’t registering, try tapping a bit faster or slower. The feature is designed to detect a quick tap, but it can be finicky.
• Use it for accessibility: Back Tap can be a great help if you have limited hand mobility—you can trigger actions without reaching across the screen.

Troubleshooting

Back Tap isn’t working at all:

• Make sure your iPhone is running iOS 14 or later. Go to Settings > General > Software Update to check.
• Ensure Back Tap is enabled in Settings > Accessibility > Touch > Back Tap. Both double and triple taps should have an action selected (not “None”).
• Remove any case or screen protector that might interfere. Test without them.
• Restart your iPhone. Sometimes a simple reboot fixes detection issues.

Back Tap works intermittently:

• Tap more firmly and deliberately. The feature relies on the accelerometer, so a gentle touch won’t register.
• Try tapping slightly above the Apple logo (about the middle of the back). That area tends to be more sensitive.
• If you have a case, try a thinner one or test without it.

Back Tap triggers the wrong action:

• Go back to Back Tap settings and double-check which action is assigned to double vs. triple tap. You may have swapped them.
• If you accidentally trigger triple tap when you meant double tap, slow down your tapping speed.

Back Tap doesn’t work while the phone is locked:

• Back Tap generally works when the phone is locked, but some actions may require the phone to be unlocked. For example, taking a screenshot works, but opening an app might not. This is a limitation of iOS.

Frequently Asked Questions

Q: Does Back Tap work with any case?

A: Most thin cases work fine, but thick or rugged cases can reduce sensitivity. If you have issues, try without the case or tap harder.

Q: Can I use Back Tap to open a specific app?

A: Yes, you can assign a shortcut that opens an app. In the Back Tap action list, choose Shortcuts and select a shortcut that opens the app (you may need to create one in the Shortcuts app first).

Q: Will Back Tap drain my battery?

A: The feature uses the accelerometer, which is always on, so the impact is minimal. You shouldn’t notice a significant battery drain.

Q: Can I set different actions for double and triple taps?

A: Yes, absolutely. You can assign a different action to each, giving you two shortcuts.

Q: Why does Back Tap sometimes trigger accidentally?

A: This can happen if you hold the phone in a way that taps the back, or if you set it down on a hard surface. Try using a case or adjusting your grip. You can also assign less disruptive actions to avoid accidental triggers.

Q: Does Back Tap work on all iPhones?

A: Back Tap is available on iPhone 8 and later, including all models that support iOS 14. It does not work on older models.
