The iPhone lock button is surprisingly versatile. While many owners likely use it to switch their device on and off (and of course lock their device as needed) it can actually do a whole lot more than just those basic functions.
Unlocking the full potential of the iPhone lock button only takes a matter of seconds.
Once you’ve enabled a single setting you can use the button to perform all sorts of tasks. These range from activating your smartphone’s zoom function to switching on Voice Control which allows you to navigate your iPhone with just your vocal cords. And those are just two of the more than 15 different functions you can map to the lock button.
This hidden feature is called Accessibility Shortcut and, once switched on, it’s activated by triple clicking your iPhone's lock button. It’s just one of the dozens of hidden iPhone features that you really should know about in order to get the most out of your Apple smartphone.
If you’re unsure how to access Accessibility Shortcut, you’ve come to the right place. Below you’ll find an easy-to-follow guide that will walk you through the simple steps to switching on this super useful iPhone hidden feature. Also be sure to check out our iOS 17 guide to see all the new features coming to your iPhone.

3. Select Accessibility Shortcut
In the Accessibility submenu, select Accessibility Shortcut. You will find this option right down at the bottom so you’ll need to scroll down first.
4. Choose your desired feature(s)
Choose your desired accessibility feature that will activate when you triple-click your iPhone’s lock button. You'll know when an accessibility feature has been selected as a small blue tick will appear to the right. You can select multiple features at this stage.
5. Triple-click the lock button to activate
Now just triple-click the lock button to activate your selected feature. If you opted to enable multiple accessibility features, a small pop-up menu will appear where you can select which feature you want to use.
And that’s how you turn on Accessibility Shortcuts on iPhone.

Fortunately, Apple accounted for this and allows you to select as many as you need.
