If your iPhone is running iOS 14 or later, you can now take a screenshot by simply tapping your back thanks to a new accessibility feature called Back Tap, which you must configure for the task. How to set it up.
How does Back Tap work?
Back Tap, first introduced in iOS 14, uses the accelerometer in your iPhone to detect if you have tapped the back of the device. In Settings, you can configure two or three taps to start certain actions on your phone. Apple believes this is an accessibility feature, but it can be useful for anyone.

How to take a screenshot by tapping your iPhone
Normally you would take a screenshot with a combination of physical buttons on your iPhone, but it is easy to fumble them and accidentally lock your iPhone or adjust the volume. With this tip, a quick screenshot is just two or three taps away.

First open “Settings” by tapping the gray “Gear” icon. You can usually find it on the first page of your home screen. If not, try Spotlight Search or Ask Siri.
Touch “Accessibility” in Settings.
Touch “Touch” on the next screen.
On the “Touch Settings” screen, scroll down until you see the “Back Tap” option, then tap it.
In the “Back Tap” settings, you can choose to assign the screenshot action to either 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 the list until you find “Screenshot” and then select it.
Then go back to a menu level to make sure your selection is saved and then exit Settings.
The next time you tap two or three times (depending on which setting you choose) on the back of your iPhone, iOS will take a picture of your iPhone’s current screen and save it in an image file. The screenshots you take are saved as usual in your photo album and can be viewed later in the Photos app. Have fun!
