It might look like a useless icon – but it’s hiding a big secret.

Tapping it can actually perform a whole range of tasks – it’s a great hack to know.

The TikTokker shared the video to his account – and here’s how it works.

In iPhone settings, there’s an option to enable a feature called Back Tap.

Simply tapping two or three times on the back of the phone can perform multiple functions.

Fans took to social media to share their delight.

One commented: “Today my life has been changed.”

A second added: “Okay I’m actually amazed right now.”

A third chimed in: “Omg no way.”

One of the most popular is having the iPhone take a screenshot – to save you fiddling with multiple physical buttons.

You can also use it to launch Shazam.

Shazam – now owned by Apple – will scan audio nearby and identify a song that’s playing.

So if you hear a track you like, you can use Back Tap to very quickly name the track.

It’s much easier than manually loading up an app.

How to use Back Tap on iPhone

To turn on the feature make sure you’ve updated to iOS 14 or later. To do that, go to Settings > General > Software update.

Then go to your Settings.

Scroll down and tap “Accessibility” and then click “Touch”.

Then scroll down to “Back Tap”.

You’ll have the choice to turn on “Double Tap” or “Triple Tap”.

Whichever you select gives you the same options.

Click to see which features you can now control with either a double or triple tap on the back of your phone.

They include taking screenshots, turning the volume up or down, magnifying, scrolling and more.

For example, if you wanted to use a Double Tap to take screenshots, click the “Double Tap” option and then tick “Shazam Shortcut” or “Screenshot”.

Now you should be able to take a screenshot just by tapping the back of your phone twice.

Bear in mind that this feature might not work if you have a thick phone case.

You can switch the features Back Tap controls or turn it off anytime by using the same steps above.

If you want two different functions, opt for one on Double Tap and another on Triple Tap.

There’s plenty of other hacks to get the most out of your iPhone.

An Instagram page have revealed a quick and easy hack to charge your device up quicker.

The facts account claimed that putting your iPhone in Airplane mode would speed up the charging time.
