It's a safe bet that you're not using all the productivity tools offered on your iPhone. It is certain that they are not useful to all. But it is still surprising to see that since the arrival of iOS 14, a significant number of iPhone users are unaware that a new button has appeared on the back of their smartphone.

Magical or transparent enough to be forgotten, we think it deserves a little more attention.

For once, this new tool can save everyone time. Apple leaves you completely in control of its configuration so that it can find a use for it. Enough announcement effects, this new button placed on your iPhone was activated when iOS 14 arrived. Called "back tap", it activates a shortcut feature by double clicking on the back surface of the Iphone.

Fully tactile, you will understand, it allows you to add an action to any smartphone application or feature.

An unknown button, so practical

To activate and configure "Back tap", nothing could be simpler: go to the settings, the Accessibility menu then the "Touch" tab. Here you will be able to find the functionality which is called in French “Toucher le dos de l’acteur”. Once activated, it is possible to configure two shortcuts depending on whether it is a double tap or a triple tap with the finger.

Below is a short guide to activating the button. We performed the manipulation on an iPhone 12. The feature is also available on iPhone X and iPhone 11, in each of their versions.

Apple has integrated the button very well so that it can recognize an involuntary touch from an intentional gesture. In the current situation with containment, why not use the shortcut to tell our iPhone to display our certificate in digital format?

Its usefulness can be summed up as follows, but the possibilities of action are gigantic. Some will prefer to use it for example to take a screenshot, others to go to their favorite social network.
