Your smartphone probably has far more capabilities than you use every day.

Most people use their phones for calls, messages, social media, photos, videos, navigation, and web browsing. But hidden beneath those familiar features are dozens of useful tools that can make everyday tasks easier, faster, and more convenient.

Some of these functions are built directly into iPhone and Android devices, while others depend on the specific operating system or phone manufacturer. The exact names and menus may vary, but the basic ideas are widely available.

Here are 10 lesser-known smartphone functions worth exploring.

1. Turn Your Phone Into a Document Scanner

You don't necessarily need a dedicated scanner to digitize a document.

Modern smartphones can use their cameras to scan receipts, forms, notes, contracts, and other papers.

On many phones, scanning tools can automatically detect the edges of a document, correct perspective, improve readability, and save the result as a PDF or image.

On iPhone, for example, the Notes app includes a document-scanning function. Many Android phones also offer document scanning through built-in camera or Google-related apps.

This can be incredibly useful when you need to:

• Save a receipt

• Send a signed form

• Digitize handwritten notes

• Store important documents

• Create a PDF quickly

Instead of taking an ordinary photo and manually cropping it, the scanning feature can do much of the work for you.

2. Use Your Camera to Recognize and Understand What You See

Your phone's camera can do more than take pictures.

Visual recognition tools can identify objects, plants, animals, landmarks, products, and even text.

Depending on your device, you may be able to point the camera at something and receive information about it almost instantly.

This can be useful when you're traveling or simply curious about something around you.

For example, you might photograph an unfamiliar plant and use a visual-search feature to find possible matches.

You can also use your camera to recognize text and then copy it into another app.

A printed sign, handwritten note, menu, or document can sometimes be converted into selectable text without manually typing everything.

3. Copy Text Directly From a Photo

This is one of those features that can feel like magic the first time you use it.

Many modern smartphones can recognize text inside an image.

Imagine you take a picture of a restaurant menu.

Instead of manually typing the address, phone number, or a particular phrase, you may be able to select the text directly from the photograph.

You can then:

Copy it.

Translate it.

Search for it.

Share it.

Call a number.

Open an address in Maps.

On supported iPhones, this functionality is associated with Live Text. Android devices can provide similar functionality through Google Lens and other built-in tools.

It turns your camera into a surprisingly capable text-recognition device.

4. Your Phone Can Read Text Aloud

If you're dealing with a long article, document, or webpage, your smartphone may be able to read portions of the content aloud.

Accessibility features can convert on-screen text into speech.

This can be useful when:

• Your eyes are tired

• You're multitasking

• You're having difficulty reading small text

• You want to listen to an article

• You're using accessibility tools

The exact settings differ between iOS and Android, but both platforms offer powerful accessibility features designed to make phones easier to use.

These tools are especially valuable because they aren't limited to people with disabilities.

Anyone can use them when circumstances make reading inconvenient.

5. Use Your Phone as a Level

Here's a simple feature that many people overlook.

Your smartphone contains motion and orientation sensors that can be used to determine whether a surface is level.

Many phones include a level tool either directly in a utility app or through another built-in feature.

It can be handy when you're:

• Hanging a picture

• Installing a shelf

• Adjusting furniture

• Checking a tabletop

• Doing a small DIY project

You don't need to find a traditional spirit level for a quick measurement.

Just place the phone carefully on the surface and check the reading.

Of course, for professional construction work, a dedicated calibrated tool may still be preferable.

6. Turn On a Built-In Emergency Medical Profile

Your smartphone may contain emergency information that can be accessed even when the phone is locked.

On supported devices, you can add information such as:

• Emergency contacts

• Allergies

• Certain medical information

• Blood type

• Other details you choose to provide

The purpose is straightforward: help emergency responders or other people obtain important information if you're unable to communicate.

On iPhones, this is handled through the Medical ID feature in the Health app.

Android phones have comparable emergency-information features, although availability and setup vary by device.

It's worth checking these settings because emergency information is most useful when it has already been configured.

7. Use Your Phone to Measure Objects

Your smartphone camera can sometimes act as a basic measuring tool.

On supported devices, augmented-reality measurement apps can estimate the dimensions of objects or distances using the camera.

You might use this to estimate:

• The length of a table

• The height of a piece of furniture

• The dimensions of a package

• The distance between objects

These measurements aren't always as accurate as professional measuring equipment.

But for quick household estimates, they can be surprisingly useful.

For example, before buying a new piece of furniture, you could use your phone to get a rough idea of whether something will fit in a particular space.

8. Create a Shortcut Instead of Repeating the Same Tasks

One of the most powerful hidden abilities of modern smartphones is automation.

Instead of manually performing the same sequence of actions every day, you may be able to create a shortcut or automation.

For example, a phone can potentially be configured to:

• Turn on a particular setting at a certain time

• Start a playlist

• Open a specific app

• Send a predefined message

• Activate a focus mode

• Perform several actions with one command

Apple's Shortcuts app provides extensive automation capabilities.

Android devices can also offer automation through built-in features or compatible applications, depending on the manufacturer and software version.

Once you start using automation, your phone can feel much more personalized.

9. Search Through Your Photos Using Natural Language

If you've had a smartphone for years, you probably have thousands of photographs.

Finding one specific image can feel impossible.

Fortunately, many modern photo apps can automatically analyze images and make them searchable.

Instead of scrolling endlessly, you may be able to search for terms such as:

"beach"

"dog"

"birthday"

"car"

"mountain"

"food"

The exact capabilities depend on your phone and photo service.

Some systems can also organize photos by people, places, dates, objects, or events.

This means your photo library can function more like a searchable database than a simple folder of images.

10. Your Phone Can Help You Find Itself When It's Lost

One of the most useful features is also one that people sometimes forget to activate.

Apple devices can use Find My, while Android devices can use Google's device-finding services.

When configured correctly, these systems can help you locate a misplaced phone.

Depending on the device and settings, you may be able to:

• See its approximate location

• Make it play a sound

• Lock the device

• Display contact information

• Mark it as lost

• Remotely erase certain data

This can be extremely useful when your phone disappears somewhere inside the house—or when you accidentally leave it somewhere else.

The important part is setting up the feature before your phone goes missing.

Bonus: Your Phone May Have Even More Hidden Tools

These 10 functions are only the beginning.

Depending on your smartphone, you may also have features such as:

• One-handed keyboard modes

• Back-tap gestures

• Screen recording

• Built-in QR scanning

• Call screening

• Password management

• Wi-Fi password sharing

• Offline maps

• Focus modes

• Hearing accessibility tools

• Custom voice commands

• Battery health information

• Screen-time monitoring

• Personal hotspot functionality

Some features are available only on certain operating-system versions or phone models.

That's why exploring your phone's Settings, Accessibility, Camera, Photos, and Security sections can reveal tools you may never have noticed.

Why So Many Useful Features Stay Hidden

Smartphones have become incredibly sophisticated.

A modern phone contains cameras, microphones, GPS, accelerometers, gyroscopes, biometric sensors, processors, wireless radios, and increasingly powerful software.

The problem is that manufacturers can't place every capability directly on the home screen.

If they did, the interface would become overwhelming.

Instead, many useful functions are tucked away inside menus, apps, gestures, or accessibility settings.

That's why two people can own the same phone and use completely different portions of its capabilities.

One person may use it primarily for social media, while another uses the same device as a scanner, navigation system, camera, translator, measuring tool, and personal assistant.

A Few Privacy Tips Before Using Smart Features

Convenience isn't the only consideration.

Many smartphone features rely on access to information such as your location, photos, microphone, contacts, or camera.

Before enabling a new feature, take a moment to check its permissions.

Ask yourself:

• Does this app really need access to my location?

• Does it need my entire photo library?

• Can I limit access to selected photos?

• Do I need microphone access all the time?

• Is the feature processing information on the device or through an online service?

You don't have to avoid useful technology.

The goal is simply to understand what information you're allowing an app or service to access.

Your Smartphone Is More Than a Communication Device

It's easy to think of a smartphone as a device for calling, texting, watching videos, and browsing social media.

But underneath the familiar interface is a surprisingly powerful collection of tools.

It can scan documents, recognize text, identify objects, measure spaces, provide emergency information, automate repetitive tasks, organize photographs, and help locate itself when lost.

And that's only a small selection of what's available.

The next time you upgrade your phone, don't immediately assume the newest features are the only interesting ones.

Take a few minutes to explore the settings and built-in apps already sitting on your device.

You might discover that the feature you've been wishing your phone had has actually been there the entire time.
