As one of the most popular smartphones in the world, the iPhone is packed with handy features. Apple's iOS has many hidden cool iPhone hacks that enable you to use your device to its fullest potential.

Want to learn more about these small, hidden features on your iPhone? Let's look at some of the best iPhone hacks and tricks you need to try on your device.

1. Adjust the Brightness of Your iPhone's Flashlight

If you're new to using an iPhone, we recommend checking out our top iPhone tips for complete beginners. But let's face it, even if you're a long-time user, you probably have been blinded at least once by your iPhone's flashlight.

That's because the default brightness is at 100% for some reason. You can adjust the flashlight brightness if you don't need this overpowering amount of light.

Access your iPhone's Control Center and long-press the Flashlight icon. There are four levels of brightness. Tap and swipe downwards to lower the brightness.

2. Do a Voiceover While Recording Your iPhone Screen

The screen recording feature on your iPhone records system sounds. But what if you want to provide some commentary or verbal explanation in addition to your screen's content?

To do so, go to the Control Center and long-press the Screen Recording icon. Tap the Microphone button to turn it on. This setting records sound in your surroundings, thus enabling you to do a voiceover while you record your iPhone screen.

3. Use the Volume Buttons to Take a Photo

As the Shutter button is located close to the bottom of your screen, you've likely almost dropped your iPhone when taking a picture more than once.

So, try out this cool iPhone hack to guarantee your iPhone's safety. Instead of the Shutter button, press either the Volume Up or Volume Down button once to snap your photo.

If you also want to use the Volume buttons to take burst photos, you'll need to go to Settings > Camera and toggle on Use Volume Up for Burst. This way, pressing and holding down on the Volume Up button lets you take a burst.

4. Take a Picture While Recording a Video

5. Apply Fun Effects to iMessages

When it comes to modern text messaging, we have stickers, memes, and emojis. But a cool iPhone hack that makes iMessages even more fun is the effects you can add to your texts.

First, select an existing iMessage thread or compose a new iMessage and fill in the recipient field. Type your message in the Text Message field, then long-press on the blue Send icon to view the effects available. Message bubble effects include Invisible Ink, Loud, and more. Screen effects offer exciting visuals such as Confetti, Balloons, and Fireworks.

To unfreeze your screen, simply press the button three times again, enter the Guided Access passcode, and confirm by tapping End.

10. Use Your iPhone as a Measuring Tool

Did you know you can use your iPhone to measure length, width, and height? There's a built-in app called Measure on your iPhone. Launch it and select the Measure tab.
