Hidden button on your iPhone: tap the back
Your iPhone has more buttons than you think. In fact, you probably don't use the most useful button at all. It's on the back. Since iOS 14, you can activate all sorts of functions by simply tapping the back of your device. Open the camera, take a screenshot, turn on the flashlight—whatever you want. Yet, almost no one knows about this function.
But here's the kicker: this hidden button works even with a case on. And with your AirPods in, you can even pause music. The beauty is that you control what happens with two or three taps. No fiddling around with buttons or opening apps. Just tap where your hand is already. It works on all iPhones with Face ID, so check that your accessories aren't interfering with this clever trick.

The back as an invisible button
Since iOS 14, Apple has added a special feature that most users still don't know about. By simply tapping the back of your device twice or three times, you can immediately activate a preset function. The great thing is that this feature works on all models with Face ID, from the iPhone X to the latest generations.
This clever addition transforms the back of your phone into an extra control button. No more navigating menus or searching for apps. A few taps are all it takes to turn on your flashlight, take a screenshot, or open the control panel. It even works perfectly with most protective cases, although very thick ones may affect sensitivity.
Popular applications in practice
The options are surprisingly extensive. Many users set the double-tap to take screenshots, while the triple-tap is often used for the flashlight. But you can also choose:
- Instantly open the camera for quick photos
- Lock screen without pressing any button
- Activate control panel for WiFi or Bluetooth
- Show notifications without swiping
- Open accessibility menu
- Mute volume during meetings
- Navigate back to home screen
For music lovers, the combination with AirPods is extra convenient. You can set the tap function to pause music or skip to the next track. This also works while exercising, when your phone is in an armband.
How to activate the tap function
Setting up this hidden button is surprisingly simple. Navigate to the Settings app on your device and follow these steps:
- Open 'Settings' on your home screen
- Scroll to 'Accessibility'
- Select 'Touch' under the physical and motor options
- At the very bottom, select 'Tap on back'
- Choose between 'Double tap' or 'Triple tap'
- Select the desired action from the list
You can assign different functions to both options (double and triple), creating two shortcuts that are always within reach. The system is smart enough to distinguish between intentional taps and accidental touches in your pocket.
Create your own shortcuts with Siri Shortcuts
For those who want more control, Apple offers the option to connect custom shortcuts to the tap function. You can do this via the Shortcuts app (formerly Siri Shortcuts). This allows you to automate more complex actions, such as:
- Call a specific contact directly
- Send a preset message
- Control multiple smart home devices simultaneously
- Start a navigation route home
- Open certain app combinations
To create your own shortcut, open the Shortcuts app and tap the plus sign. Then, build your desired action step by step. Give it a meaningful name, as it will appear later in the selection menu under the tap function settings.
Tips for optimal use
The sensitivity of the tap function varies by model and situation. Newer devices generally respond better than older ones. A few practical tips:
It works best when you tap with your fingertips, roughly in the middle of the back. Very light taps won't register, but you don't need to tap hard either. Rhythm is more important than force. Double-tapping requires rapid succession of taps, similar to double-clicking with a computer mouse.
Some users report that very thick or rubber cases can hinder functionality. Thin plastic or silicone protectors usually don't pose a problem. Try it out with your specific combination of device and accessories.
Battery consumption and performance
A common question is whether this feature uses extra battery. Apple designed the feature to minimize its impact. The device uses the accelerometer, which is already active for other functions. In practice, you won't notice any difference in battery life.
The feature also works perfectly on older models with Face ID running iOS 14 or later. Even a refurbished iPhone 11 or 12 supports all features without any issues. This makes it a valuable addition for anyone who wants to get the most out of their current device without upgrading.
Conclusion: a useful feature that saves you time
The tap function on the back is a surprisingly handy addition that makes your daily use much more efficient . It takes five minutes to set up, uses minimal battery, and even works with a case on your phone. Whether you want to take a quick screenshot, use your flashlight, or pause music with your AirPods —two taps are all it takes.
This feature proves that even a refurbished iPhone with Face ID can still learn new tricks. Just give it a try and discover which shortcuts are most useful to you.
