Most iPhone users know the basics taking photos, using Face ID, sending messages and browsing the web. But tucked away inside iOS are several incredibly useful features that many people never discover.
These aren’t flashy gimmicks. They’re practical tools that can make everyday use of an iPhone faster, smarter and more convenient.
Here are five hidden iPhone features worth knowing.
1. Back Tap: Turn the Back of Your iPhone Into a Button
One of the most surprising hidden features is Back Tap.
Instead of touching the screen, users can simply double-tap or triple-tap the back of their iPhone to perform an action. It can be set to take a screenshot, open the Control Center, activate the flashlight, launch a shortcut and much more. Back Tap is available on iPhone 8 and later running supported versions of iOS.
How to activate it
- Open Settings
- Go to Accessibility
- Tap Touch
- Scroll down to Back Tap
- Choose Double Tap or Triple Tap
- Select the action you want
Once configured, the feature works with just a quick tap on the back of the phone.
2. Live Text: Copy and Translate Text From Anything
Imagine seeing a phone number on a poster or a paragraph inside a book and being able to copy it without typing.
That’s exactly what Live Text does.
Live Text recognizes text inside photos, videos and even through the Camera app. Users can copy text, translate languages, search selected words online, call detected phone numbers or open websites directly from text found in an image. It is available on supported iPhones and languages, with availability varying by region.
How to use it
- Open the Camera or Photos app
- Point the camera at text or open a photo containing text
- Tap the Live Text icon
- Select the text
- Copy, Translate, Look Up or Share
It’s especially useful for students, travelers and anyone who regularly works with documents.
3. Reachability: Easily Use a Large iPhone With One Hand
As iPhones have become larger, reaching the top of the screen with one hand can be difficult.
That’s where Reachability comes in.
This accessibility feature temporarily lowers the top half of the screen, making buttons and menus easier to reach without changing the phone’s size. Apple includes Reachability as one of the built-in touch accessibility options on supported iPhones.
How to activate it
- Open Settings
- Go to Accessibility
- Tap Touch
- Turn on Reachability
After enabling it, swipe downward near the bottom edge of the screen on Face ID iPhones to bring the top content closer.
It’s a simple feature that becomes surprisingly useful once you get used to it.
4. Sound Recognition: Let Your iPhone Listen for Important Sounds
Your iPhone can do more than listen to your voice—it can also recognize certain environmental sounds.
With Sound Recognition, the iPhone can listen for sounds such as a doorbell, smoke alarm, baby crying, sirens and several other supported alerts, then send a notification when it detects them. Apple lists Sound Recognition among its hearing accessibility features.
How to activate it
- Open Settings
- Go to Accessibility
- Tap Sound Recognition
- Turn it on
- Choose the sounds you want the iPhone to recognize
It’s primarily designed as an accessibility feature, but it can also be useful in everyday situations when someone wants an extra layer of awareness around them.
5. Visual Look Up: Identify Objects From Your Photos
Ever taken a picture of a flower, animal or famous landmark and wondered what it was?
Visual Look Up can help identify many recognizable subjects directly from the Photos app.
Depending on the image and availability, the feature can provide information about plants, animals, landmarks, artworks and other objects detected in supported photos. Apple’s visual intelligence tools continue expanding these image-recognition capabilities across modern iPhones and supported software.
How to use it
- Open a photo in Photos
- Swipe up or tap the information button
- Look for the Visual Look Up option if available
- Tap it to view related information
It’s a great feature for travelers, nature lovers and anyone curious about the world around them.
The best iPhone features aren’t always the ones Apple talks about the most.
Features like Back Tap, Live Text, Reachability, Sound Recognition and Visual Look Up are quietly built into iOS and can genuinely improve how people use their devices every day. Whether it’s copying text from a book, taking screenshots without pressing buttons or identifying something in a photo, these hidden tools show that there’s often much more inside an iPhone than most users realize.
