The Volume Buttons on Your Phone Aren’t Just for Sound: 6 Hidden Functions Most People Don’t Know About

Most people use the volume buttons on their smartphone for one simple purpose: turning the sound up or down.

But depending on your phone model, operating system, and the app you're using, those two physical buttons can do much more. They can help you take photos, control video recording, silence incoming calls, activate accessibility features, and perform other shortcuts that can make everyday phone use much easier.

Not every function works on every device, so some shortcuts may differ between iPhone, Samsung Galaxy, Google Pixel, and other Android phones.

Here are six useful volume-button functions worth knowing.

1. Use the Volume Button as a Camera Shutter

One of the most useful tricks is also one of the easiest.

On many smartphones, pressing either volume button while using the camera can capture a photo.

This can be especially convenient when holding the phone horizontally. Instead of reaching toward the on-screen shutter button, you can place your finger naturally on the side of the phone and press the volume key.

On some phones, the volume buttons can also be configured for additional camera functions.

For example, depending on the camera app and device settings, a volume button may be assigned to:

• Take a photo

• Start or stop video recording

• Zoom

• Control camera exposure or another camera function

This can make taking photos much easier when you are trying to keep the phone stable.

Tip: If your phone supports volume-button camera controls, check the Camera settings to see exactly what your model allows.

2. Quickly Silence an Incoming Call

Imagine your phone starts ringing during a meeting, at a restaurant, or while you're watching a movie.

You don't necessarily need to unlock the phone or answer the call.

On many smartphones, pressing a volume button can silence the incoming ringtone without rejecting the call.

The caller can still continue hearing the normal ringing tone on their end, while your phone stops making noise.

This is particularly useful when you don't want to draw attention to your phone.

The exact behavior can vary by device, so test it once before relying on the shortcut in an important situation.

3. Control Video Recording Without Touching the Screen

On some smartphones and camera applications, the volume buttons can be used to start or stop video recording.

This can be useful when the phone is mounted on a tripod, positioned at an awkward angle, or being used for hands-free recording.

Instead of reaching toward the screen, you can press a physical button on the side.

Some camera apps also allow volume buttons to perform different actions depending on the shooting mode.

For example, one device might use the button as a shutter, while another may allow it to control zoom.

This is particularly useful for people who record cooking videos, demonstrations, workouts, tutorials, or social-media content.

4. Use Volume Buttons for Accessibility Shortcuts

Here's a feature that can be genuinely useful for people who rely on accessibility tools.

Certain Android devices support accessibility shortcuts involving the volume keys. On supported phones, pressing and holding both volume buttons simultaneously can activate an assigned accessibility feature.

Depending on the device and configuration, this may provide quick access to features such as:

• TalkBack

• Magnification

• Accessibility menus

• Other device-specific accessibility services

The exact shortcut depends on your Android version and manufacturer.

On iPhone, accessibility shortcuts are configured differently and generally use other physical-button combinations rather than simply pressing the volume keys together.

If you don't need accessibility shortcuts, there's no reason to activate them accidentally. But if you or a family member relies on accessibility features, knowing where these shortcuts are can be extremely helpful.

5. Take Screenshots With the Volume Button

This is one of the most familiar shortcuts, but many people still don't realize how useful it can be.

On many smartphones, pressing a combination of the power/side button and a volume button takes a screenshot.

For example, many Android phones use:

Power/Side button + Volume Down

iPhones use different combinations depending on the model. iPhones with Face ID generally use the Side button + Volume Up combination.

A screenshot can be useful for saving:

• Online receipts

• Directions

• Important messages

• Confirmation pages

• Product information

• Social-media content

• Error messages

The exact combination depends on the phone, so if the shortcut doesn't work, check your device's official instructions.

6. Use Volume Buttons to Control Music and Media

Volume buttons naturally control audio levels, but their usefulness goes beyond simply making music louder or quieter.

Depending on the phone, headphones, connected accessories, and media app, physical buttons may interact with playback controls.

Some Bluetooth headphones and earbuds have their own volume controls or customizable button gestures. Certain third-party apps may also offer additional shortcuts.

However, the volume buttons on the phone itself generally control volume rather than directly functioning as universal play/pause or track-skipping buttons.

That's an important distinction because online posts sometimes claim that every smartphone can use volume buttons to skip songs or perform multiple universal media controls.

In reality, functionality varies considerably between devices and apps.

Bonus: Change Which Volume You're Controlling

Here's another feature many people overlook.

Modern smartphones often separate different audio categories, such as:

• Media volume

• Ringtone volume

• Notification volume

• Alarm volume

• Call volume

Pressing a volume button usually changes the currently relevant volume, but tapping the expanded volume panel may give you access to additional sliders.

This is useful when your music is too loud but your ringtone is too quiet—or when you want to adjust alarm volume without changing media volume.

Knowing the difference between these volume controls can prevent some surprisingly annoying situations.

Why These Shortcuts Matter

Physical buttons can sometimes be faster and more reliable than touchscreen controls.

If your hands are wet, you're wearing gloves, the phone is mounted somewhere, or you're trying to capture a spontaneous moment, reaching for a physical button can be much easier than tapping a small icon.

They can also improve accessibility for people who find touchscreen gestures difficult.

But there's an important catch: smartphone manufacturers don't all implement these shortcuts in the same way.

An option available on a Samsung Galaxy may not work on a Google Pixel. An iPhone shortcut may use a completely different button combination.

Even software updates can change how certain features behave.

How to Find Your Phone's Hidden Button Features

If you want to discover what your own phone can do, start with the device's settings.

On Android, look through areas such as:

Settings → Accessibility

and

Camera Settings

You can also search Settings for terms such as “volume button,” “shortcut,” “accessibility,” or “camera.”

On iPhone, check:

Settings → Accessibility

and

Settings → Camera

You can also search the Settings app for specific features.

If a shortcut doesn't work, don't assume your phone is broken. It may simply not support that particular function or may require the feature to be enabled first.

Don't Believe Every “Secret Phone Trick”

Social media is full of posts claiming that a certain button combination can unlock hidden features on every smartphone.

Some of these tricks are real.

Others only work on specific models, specific operating-system versions, or particular apps.

The safest approach is to verify the feature for your exact device.

Avoid downloading unknown applications just because a video claims they are necessary to unlock a “secret” function. Some apps may request unnecessary permissions or access to personal information.

Your phone's official documentation and settings are usually the best place to start.

The Bottom Line

Those small volume buttons on the side of your smartphone can be surprisingly useful.

Depending on your device, they may help you take photos, control camera functions, silence incoming calls, activate accessibility shortcuts, take screenshots, and manage different types of audio.

The exact features vary between iPhone and Android devices, and even between different Android manufacturers.

So the next time you reach for the volume button, remember that it may be doing more than simply making your music louder.

Explore your Camera, Accessibility, and Sound settings—you might discover a shortcut that saves you time every single day.
