How to use the secret back button on the iPhone

If you’re looking to make use of the iPhone’s little-known but very handy Back Tap button, here’s a guide on how to set it up.

You might think that all the buttons on your iPhone are obvious, from the side button to the volume keys, to the ring/silent toggle (or Action Button on the iPhone 15 Pro series). However, there’s an extra one hiding in plain sight that’s rarely mentioned – and it’s none other than the back panel itself, adorned with that alluring Apple symbol.

The functionality allows you to activate various actions simply by double- or triple-tapping the rear of the phone, making it easy to access apps like Camera or toggle the torch on.

Here’s how you can put it into action and reprogram it for your own uses.

Why is this button “secret”?

This is a neat feature, so it’s a bit of a puzzle why Apple has chosen not to draw much attention to it – but it’s simply not all that well known among the wider public, and that’s what makes it seem relatively “secret” at least by comparison to the other buttons you’re likely to use every day.
