iPhone Hidden Rear Button: How to Use It

Updated · Standard formula, shown below

The iPhone’s hidden rear button isn’t a physical button—it’s a gesture-based shortcut called Back Tap. It lets you trigger actions like taking a screenshot, opening Control Center, or launching a custom shortcut by double-tapping or triple-tapping the back of your iPhone. This guide walks you through setting it up, customizing it, and fixing common issues.

What You’ll Need

  • An iPhone running iOS 14 or later (Back Tap is available on iPhone 8 and newer, including all iPhone SE models).
  • Access to the Settings app.
  • Optional: The Shortcuts app (pre-installed) if you want to create custom actions.

Step-by-Step

  1. Open Settings. Tap the gray gear icon on your home screen.
  2. Go to Accessibility. Scroll down and tap Accessibility.
  3. Tap Touch. Under the Physical and Motor section, tap Touch.
  4. Scroll to Back Tap. At the very bottom of the Touch menu, you’ll see Back Tap. Tap it.
  5. Choose Double Tap or Triple Tap. You’ll see two options: Double Tap and Triple Tap. Tap the one you want to configure first. (You can set different actions for each.)
  6. Select an action. Scroll through the list of system actions (like Screenshot, Control Center, Notification Center, Mute, etc.) or scroll to the bottom to choose a Shortcut you’ve created. Tap the action to assign it.
  7. Test it. Exit Settings and tap the back of your iPhone twice (or three times) near the Apple logo. The assigned action should trigger.

Common Mistakes

  • Tapping too hard or too soft. Back Tap uses a tap gesture, not a press. A firm, quick tap works best—too hard might be registered as a different gesture, and too soft won’t register at all.
  • Using a thick case. Some bulky cases can interfere with the sensitivity. If it’s not working, try removing the case temporarily.
  • Confusing Double and Triple Tap. Make sure you’re tapping the correct number of times. If you set an action for Double Tap and you tap three times, it won’t trigger.
  • Expecting it to work on the screen. Back Tap only responds to taps on the back glass, not the screen or sides.

Tips

  • Use it for frequent actions. Screenshot, Control Center, and Notification Center are popular choices because they save reaching to the top of the screen.
  • Create custom shortcuts. In the Shortcuts app, you can build a shortcut that does multiple things (e.g., turn on Low Power Mode and set brightness to 50%) and assign it to Back Tap.
  • Set both taps. Use Double Tap for one action and Triple Tap for another. For example, Double Tap for Screenshot, Triple Tap for Mute.
  • Adjust for your case. If you use a case, you might need to tap slightly harder or aim for the area where the case is thinnest (usually near the camera bump).

Troubleshooting

Back Tap not working at all?

  • Ensure your iPhone model supports it (iPhone 8 or later, all SE models).
  • Check that you’ve assigned an action to both Double Tap and Triple Tap—if you only set one, the other won’t do anything.
  • Restart your iPhone. Sometimes a simple reboot clears minor glitches.
  • Remove any case or screen protector that might be interfering.
  • Go to Settings > Accessibility > Touch > Back Tap and re-select the action—sometimes it doesn’t save properly.

Back Tap triggers accidentally?

  • If it activates when you set your phone down or grip it tightly, try using only Triple Tap for important actions, as it’s less likely to trigger accidentally.
  • You can also turn off Back Tap entirely if it becomes a nuisance.

Back Tap is too sensitive or not sensitive enough?

  • There’s no sensitivity setting, but you can try tapping with a different part of your finger (flat vs. tip) to find what works.
  • If it’s not registering, make sure your fingers are clean and dry—moisture or oil can affect the tap detection.

Frequently Asked Questions

Does Back Tap work with any case?

Most thin cases work fine, but thick or rugged cases can reduce sensitivity. If yours isn’t working, test without the case.

Can I use Back Tap to open an app?

Yes, but not directly. You can create a shortcut that opens an app (using the “Open App” action) and assign that shortcut to Back Tap.

Does Back Tap drain battery?

No, Back Tap uses the accelerometer and gyroscope, which are already active for other features. The impact on battery life is negligible.

Can I set different actions for Double Tap and Triple Tap?

Yes, you can assign a different action to each. They are independent settings.

Does Back Tap work while the phone is locked?

Yes, Back Tap works even when the screen is off, as long as the phone is not in your pocket (where accidental taps are likely).

Why is Back Tap not available on my iPhone?

Back Tap requires iOS 14 or later and an iPhone 8 or newer. If you have an older device or iOS version, it won’t appear in Settings.
