Back Tap Screenshot: How to Capture by Tapping

Updated · Standard formula, shown below

Yes, you can capture a screenshot by tapping the back of your iPhone — this is a built-in feature called Back Tap, available on iPhone models with Face ID (iPhone 8 and later with iOS 14 or newer). You assign the “Screenshot” action to either a double-tap or a triple-tap on the back of the phone, and then any two or three quick taps will save a screenshot instantly. This guide explains how to set it up, what to do if it isn’t working, and how it compares to other screenshot methods.

What Is Back Tap and How It Works

Back Tap uses the iPhone’s built-in accelerometer and gyroscope to detect a physical tap on the rear glass. When you tap twice or three times, the phone registers the impact and triggers whatever action you’ve assigned in Settings. It doesn’t require any extra hardware or app — it’s part of iOS’s accessibility features, so it works on any supported iPhone after you enable it.

You can assign two different actions: one for double-tap and one for triple-tap. For example, you could set double-tap to take a screenshot and triple-tap to open the Control Center. The feature is designed for people who have difficulty pressing physical buttons, but it’s useful for anyone who wants a quicker way to capture the screen.

How to Set Up Back Tap for Screenshots

Setting up Back Tap takes less than a minute. Follow these steps on your iPhone:

  1. Open Settings.
  2. Tap Accessibility.
  3. Tap Touch (under “Physical and Motor”).
  4. Scroll down and tap Back Tap.
  5. Choose Double Tap or Triple Tap.
  6. Scroll through the list and select Screenshot.

That’s it. Now tap the back of your iPhone twice (or three times, depending on what you chose) to capture a screenshot. The screenshot saves to your Photos app just like any other screenshot.

If you want both gestures to do something, assign a different action to the other one. For instance, many people set double-tap to Screenshot and triple-tap to Mute, or vice versa.

Which iPhone Models Support Back Tap

Back Tap requires the hardware to detect taps, which means it’s available on all iPhones with Face ID — that includes the iPhone 8 and later, including the iPhone SE (2nd and 3rd generation). It does not work on older iPhones with a Home button, such as the iPhone 7 or earlier, because they lack the necessary sensors.

Here’s a quick list of compatible models:

  • iPhone 8, 8 Plus
  • iPhone X, XS, XS Max, XR
  • iPhone 11, 11 Pro, 11 Pro Max
  • iPhone 12, 12 mini, 12 Pro, 12 Pro Max
  • iPhone 13, 13 mini, 13 Pro, 13 Pro Max
  • iPhone 14, 14 Plus, 14 Pro, 14 Pro Max
  • iPhone 15, 15 Plus, 15 Pro, 15 Pro Max
  • iPhone SE (2nd and 3rd generation)

If you have one of these, you can use Back Tap. If you have an older model, you’ll need to use the traditional button method (side button + volume up) or AssistiveTouch.

Common Problems and Fixes

Back Tap is reliable, but sometimes it doesn’t work as expected. Here are the most common issues and how to resolve them:

  • It doesn’t respond at all: Make sure you have a case that isn’t too thick. Very thick or heavy cases can dampen the tap detection. Try removing the case and test again.
  • It triggers accidentally: If you’re getting screenshots when you don’t want them, you might be tapping too hard or the phone is detecting taps when you set it down. Try assigning a triple-tap instead of a double-tap — triple-tap is less likely to trigger accidentally.
  • It only works sometimes: The tap needs to be firm and quick. A slow or light tap may not register. Also, make sure you’re tapping the back glass, not the camera bump or the edges.
  • It works but takes a screenshot of the wrong thing: Back Tap only works when the screen is on and unlocked. If you’re on the lock screen, it won’t take a screenshot (it might do nothing or trigger a different action).
  • It’s not in Settings: If you don’t see “Back Tap” under Accessibility > Touch, your iPhone is either too old or you’re not running iOS 14 or later. Update your iPhone to the latest iOS version.

If none of these fixes work, restarting your iPhone often resolves temporary software glitches.

Back Tap vs. Other Screenshot Methods

Back Tap is just one way to take a screenshot. Here’s how it compares to the others:

  • Side button + Volume Up: This is the standard method on Face ID iPhones. Press the side button and the volume-up button simultaneously. It’s fast but requires two hands or a precise grip.
  • AssistiveTouch: You can add a “Screenshot” button to an on-screen floating menu. This works on all iPhones, including older ones, but it adds an always-visible button that can get in the way.
  • Siri: You can say “Hey Siri, take a screenshot.” It works, but it’s slower and less reliable if you’re in a noisy environment.
  • Back Tap: The main advantage is that it’s completely hands-free from the buttons — you just tap the back. It’s great for one-handed use or when you have your phone in a mount. The downside is that it can be accidentally triggered, and it requires a specific tap force.

For most people, the button method is the most reliable. Back Tap is a convenient alternative, especially if you find the buttons hard to press or you want a shortcut that doesn’t require changing your grip.

Customizing Back Tap for Other Actions

Back Tap isn’t limited to screenshots. You can assign almost any system action to it, including:

  • Open Control Center or Notification Center
  • Mute or unmute
  • Lock the screen
  • Open the App Switcher
  • Take a screenshot
  • Trigger a Shortcut (from the Shortcuts app)
  • Turn on the flashlight
  • Adjust volume or brightness

To change the action, go back to Settings > Accessibility > Touch > Back Tap and select a different action for either double-tap or triple-tap. You can also set one of them to “No Action” if you don’t want to use it.

If you use the Shortcuts app, you can create a custom shortcut that does something specific — like sending a message or opening a particular app — and then assign that shortcut to a back tap. This makes Back Tap incredibly versatile.

Safety and Battery Life

Back Tap uses the accelerometer and gyroscope, which are always on anyway, so it has a negligible effect on battery life. It doesn’t drain your battery noticeably. There’s also no safety concern — it’s a software feature that simply listens for a tap pattern.

One thing to be aware of: if you have a magnetic case or a PopSocket attached to the back, it might interfere with tap detection. PopSockets can make it harder to tap the exact spot where the sensor is, and very thick cases can reduce sensitivity. If you have trouble, try removing the accessory and test again.

Frequently Asked Questions

Does Back Tap work with a case?
Yes, but a very thick case can reduce sensitivity. If it stops working, try removing the case or tapping a bit harder. Most standard cases don’t cause problems.

Can I use Back Tap on an iPad?
No, Back Tap is only available on iPhone. iPads don’t have this feature.

Why does my iPhone take a screenshot when I don’t tap it?
This usually happens when the phone is in a pocket or bag and something presses against the back. Try switching to triple-tap, which is harder to trigger accidentally, or turn off Back Tap when you don’t need it.

Can I set Back Tap to take a screenshot on the lock screen?
No, Back Tap only works when the phone is unlocked. On the lock screen, it won’t trigger any action.

Does Back Tap work with gloves?
It depends on the glove thickness. Thin gloves that allow the tap to be detected should work, but thick winter gloves may not register. You’ll need to test it.

How do I turn off Back Tap?
Go to Settings > Accessibility > Touch > Back Tap and select “No Action” for both double-tap and triple-tap. That disables it entirely.
