Your Android phone’s buttons do more than just control volume or wake the screen. With a few simple tweaks, they can double as shortcuts for snapping quick photos, skipping tracks, launching apps, or even activating emergency features.
I’m using a Samsung Galaxy phone running Android 15 (One UI 7). The availability and location of certain features may vary depending on your device’s Android version and the manufacturer’s custom skin.

The Basics
You already use the power button to lock and unlock your phone, but if you long-press it, your phone won’t turn off—instead, it’ll trigger the default digital assistant, whether it’s Gemini, Bixby, or something else. You can change which assistant it triggers, or disable this shortcut entirely, by going to Settings > Advanced Features > Side Button > Long press.
If you long-press the power button and volume down button together, you’ll see the power menu. From there, you can shut down, restart, or boot into Safe Mode (by long-pressing the Power Off icon).
When you need to share what’s on your screen, press and quickly release the power and volume down buttons together to take a screenshot on your Android phone. You’ll then see options to view, share, or delete it.

Snap Photos in an Instant
Your Android phone’s camera is more than capable of capturing stunning photos and crisp videos. However, not every moment waits for you to unlock the screen, launch the camera app, and tap the shutter. For those blink-and-you’ll-miss-it moments, your phone’s physical buttons can save the day.
On most Android devices, double-pressing the power button instantly launches the Camera app. By default, it opens the rear camera, but you can customize it to launch the video recorder, front camera, or even portrait mode. Go to Settings > Advanced Features > Side Button > Double press, tap the gear icon next to Camera, and select your preferred option.
Once the camera is open, you don’t need to tap the shutter button; press either volume button to snap a photo. This is especially handy when you’re trying to hold the phone steady or take a quick one-handed shot.
If you don’t use the camera often, you can configure that double-press shortcut for something more useful. Options include turning on the flashlight, starting a voice recording, opening the magnifier, or launching your favorite app.

Trigger Emergency Help Fast
During emergencies, every second counts. That’s why your Android phone comes with built-in emergency features that let you act fast when you need help most.
All you have to do is press the power button five times quickly for your phone to activate the Emergency SOS feature. If you’re using a Samsung phone, it only takes three quick presses. This will immediately start dialing the local emergency number. If you’ve set up emergency contacts on your phone, it will also send them a message with your real-time location.
If you’re worried about accidentally triggering an emergency call, you can adjust the countdown timer your phone uses before dialing. Head to Settings > Safety & emergency > Emergency SOS, and increase the countdown timer to whatever seems right for you.

Answer, End, or Silence Phone Calls
Answering or rejecting a phone call is usually straightforward, but what about those times when your hands are dirty, wet, or bundled up in gloves? Sure, if you’re wearing headphones that support call controls, you’re covered. But if not, your phone’s physical buttons can handle calls just as easily.
When a call comes in, press either volume button to instantly silence the ringer. It’s a quick way to mute an incoming call, even while your phone is still in your pocket.
Answering and ending calls with buttons isn’t enabled by default, but it’s easy to set up. Head to Settings > Accessibility > Interaction and dexterity > Answering and ending calls. Then, toggle on Press Volume up to answer calls and Press Side button to end calls.
That’s it; your phone calls can now be managed with a button press. Just be careful not to accidentally hang up when you meant to turn off the screen!

Unlock Hidden Accessibility Shortcuts
Android phones come packed with accessibility features that are useful for everyone. For instance, the Magnification tool turns your camera into a magnifier, while Extra dim lowers screen brightness beyond the usual minimum. You also get Live Caption, which adds subtitles to videos automatically so you can enjoy videos in a noisy environment or when you need to keep the volume down.
And thankfully, you don’t have to dig through the settings menu every time you want to use these features. You can turn your phone’s physical buttons into quick-access shortcuts instead.
Go to Settings > Accessibility > Advanced settings, then tap Side and Volume up buttons or Volume up and down buttons. From there, you can set your favorite accessibility feature to launch by simply pressing the button combination.

Control Your Music Like a Pro
There’s no need to wake your phone to skip tracks while listening to music or podcasts; long-pressing your phone’s volume buttons can let you do that. By default, Android doesn’t let you skip tracks using the volume keys, but that’s easy to change with an app.
If you’re using a Samsung Galaxy phone, get the Sound Assistant app from the Galaxy Store. Once it’s set up, turn on the Control music with Volume keys option. You can then choose whether holding volume up skips to the next track or the previous one, and do the same for volume down.
On other Android phones, grab the Volumee (yup, that’s the name) app from the Play Store. After installing, give it the necessary permissions. You’ll then be able to long-press the volume buttons to skip songs without waking the screen. The app also lets you fine-tune how long the press needs to be and whether you want vibration feedback when a track skips.

Customize Buttons to Do Almost Anything
If some of the button shortcuts mentioned earlier aren’t available on your phone, or if you want full control over what your buttons can do, get the Button Mapper app from the Play Store.
Once set up, Button Mapper lets you assign custom actions to almost every button on your device. That includes volume up, volume down, and even the button on your headset. You can set different actions for a single tap, double tap, and long press.
To start, open the app and tap the button you want to customize. Next, choose the type of press—single, double, or long—and then assign the action.
You can have a button open recent apps, launch your favorite app, call a specific contact, turn on Do Not Disturb, or even jump straight into a WhatsApp chat. There are tons of options to explore, so it all comes down to how creative get.

The number of buttons on your Android may be few, but their uses are many. With the right settings and apps, those small controls can turn into powerful shortcuts for snapping photos, launching apps, or triggering your favorite accessibility tools.
Of course, you won’t be able to use every trick at once, so make sure to pick the features that matter most to you.
