If your iPhone is running iOS 14 or later, you can now take a screenshot just by tapping its back thanks to a new accessibility feature called Back Tap, which you will need to configure for the task. Here’s how to set it up.
How does Back Tap work?
Back Tap, introduced for the first time in iOS 14, uses your iPhone’s accelerometer to detect if you’ve tapped on the back of your device. In Settings, you can configure two or three taps to launch certain actions on your phone. Apple considers this an accessibility feature, but it can be useful for anyone.
How to take a screenshot by tapping your iPhone
Normally you take a screenshot using a combination of physical buttons on your iPhone, but it’s easy to poke around and accidentally lock your iPhone or adjust the volume. With this trick, a quick screenshot is just two or three clicks away.
First, open “Settings” by tapping on its gray “Gear” icon. You can usually find it on the first page of your home screen. Otherwise, try Search Spotlight or ask Siri.
In Settings, tap “Accessibility”.
On the next screen, press “Touch”.
On the “Touch Settings” screen, scroll down until you see the “Back Tap” option, and then tap it.
In the “Back Tap” settings, you have the choice of assigning the screen capture action to two taps (“Double Tap”) or three taps (“Triple Tap”) on the back of the case. Select the option you want.
In the menu that appears, scroll down until you find “Screenshot,” and then select it.
After that, go back one menu level to make sure your selection is saved, then exit Settings.
The next time you tap the back of your iPhone two or three times (depending on the setting you choose), iOS will capture an image of your iPhone’s current screen and save it as an image file. The screenshots you take will be saved to your photo album as usual and can be viewed later in the Application of photos. Enjoy!
