A great new feature in iOS 14 is called Back Tap. As the name suggests, it allows you to customize an action performed on your iPhone by either double tapping or triple tapping the back of your iPhone. The feature is available on the iPhone 8 and later and is a handy way to perform common actions literally with a couple of taps.
The feature is in the Accessibility settings of iOS 14 and is aimed to help those with limited mobility or motor function to perform common tasks more easily and with one hand. The feature though is open to everyone and easily configurable with a wide range of actions that can be performed. Here is how you set it up.
First, open up Settings and then the Accessibility section on your iPhone. Now scroll down until you find the Touch settings and open it up.
With the Touch settings open, scroll down to the bottom of the page and you will see the Back Tap option. By default, this will be set to off because no actions have been defined. Now tap on this to open up the options.
The options for Back Tap provide you the ability to set an action based on a double tapping or triple tapping of the back of your iPhone. Each setting is independent of each other so you can have the double tap do one thing and the triple tap do another. Tapping on one of these options will bring up the list of actions you can assign to either. Once you assign an action, a checkmark is put by it on the list and you can back your way out to the options list again.
As you can see from my screenshots above, I’ve set my double tap action as going to my Home screen while my triple tap it to take a screenshot.
I’ve been testing this feature for the past couple of weeks and it works nearly flawlessly, even with a case on your iPhone. I tested it on both my iPhone 8 (my long term beta phone) and on the production release of iOS 14 on my iPhone 11 Pro. On both phones I have the Apple silicon cases and had no problem getting the tapping to work through the case.
Give it a try and see what you think. If it isn’t for you, you can always turn it off by setting the actions to None on the Actions menu.
