Apple likes to program randomly useful tools into their iPhones, like the hidden magnifying glass and the backspace shortcut on the calculator app. One of the coolest features on the device is something that's hiding in plain sight. As Simplemost reports, the Apple logo on the back of your iPhone is actually a button that can execute various tasks.

The sleek, minimalist design on your phone can become a practical piece of hardware if you know how to use it correctly. To activate it, open Settings and select Accessibility. From there, you can choose Touch and then Back Tap to program the Apple logo to do all sorts of things at the tap of your finger. Possible actions include locking your phone, taking a screenshot, adjusting the volume, scrolling up or down, and opening the Home screen. You can even program the phone to perform different tasks depending on if you double tap or triple tap the button.

If you had no idea the feature existed until now, that's because it was added fairly recently. According to The Verge, Apple included Back Tap with iOS 14, which was released in October 2020. The software update uses the pre-existing sensors in your iPhone to transform the back of the device into a brand-new button.

You can watch TikTok user Brit Brown walk you through setting up the feature in the video below. Here are even more iPhone hacks you didn't know you needed.
