Apple's first foldable smartphone, the iPhone Duo, introduces a completely different way to use an iPhone. With its large folding display, redesigned interface, and new hardware features, the device offers more flexibility than traditional iPhone models.

However, getting the best experience requires adjusting a few settings. From customizing Touch ID shortcuts to improving camera controls, several small changes can make everyday use more convenient.

If you've recently purchased an iPhone Duo, here are nine settings and features worth exploring to get more out of Apple's foldable smartphone.

1. Customize the Touch ID Experience

Unlike traditional iPhones that rely on Face ID, the iPhone Duo uses Touch ID integrated into its side button.

Take some time to familiarize yourself with its fingerprint recognition system. Registering your fingerprints correctly can make unlocking the phone, authorizing purchases, and accessing protected apps more convenient.

You can also check the accessibility settings to customize how the side button responds.

2. Adjust the Volume Button Controls

The iPhone Duo features a redesigned button layout to accommodate its folding design. This means adjusting to the volume controls may take some time, especially if you're upgrading from an older iPhone.

Explore the available button and accessibility settings to make volume adjustments easier.

Getting familiar with the new layout can save time when switching between media playback, calls, and notifications.

3. Explore the Foldable Display Settings

The iPhone Duo's biggest attraction is its large internal display. When unfolded, it provides considerably more screen space for browsing, watching videos, reading, and multitasking.

Explore display-related options to find a comfortable viewing experience. Pay attention to brightness, text size, and other available display preferences.

You should also experiment with landscape and portrait orientations to understand how different applications adapt to the larger screen.

4. Set Up Split View for Multitasking

One of the most useful features of the iPhone Duo is its ability to run two applications side by side.

Instead of constantly switching between apps, you can keep two applications open simultaneously.

For example, you can browse the web while taking notes or read an email while checking information in another application.

To get started:

1. Unfold your iPhone Duo.

2. Hold it in landscape orientation.

3. Open the first application.

4. Move the application to one side of the display.

5. Select another application for the remaining screen space.

You can also save frequently used combinations as app pairs, making it easier to return to your favorite multitasking setup.

5. Customize Camera Features

The foldable design also introduces new possibilities for photography.

The iPhone Duo allows users to take selfies using the rear cameras while viewing the composition on the outer display.

Explore the Camera app to discover additional options, including Duo Preview, which lets people in front of the camera see a live preview of the picture.

These features can be particularly useful when taking group photos or capturing pictures with friends and family.

6. Enable Kid Cue for Better Photos

Getting children to look directly at the camera can be difficult. Apple's Kid Cue feature aims to make this easier.

When enabled through the Camera app, the outer display plays animations designed to attract a child's attention toward the camera.

The feature can also be useful when photographing pets.

Although it won't guarantee perfect pictures every time, it provides another creative way to take advantage of the iPhone Duo's external display.

7. Try Smart Take for Group Photography

Smart Take is another camera feature worth exploring.

It makes taking group pictures easier by allowing you to position the iPhone Duo on a stable surface and use its foldable design to frame the shot.

Once everyone is in position, the phone can automatically capture the picture.

This reduces the need for someone to stand behind the camera or repeatedly use a timer.

8. Make Better Use of the Foldable Hinge

The iPhone Duo's hinge is more than just a mechanism for opening and closing the device.

You can partially fold the phone and position it at different angles for hands-free activities.

For example, you can use it as a small display for watching videos, making FaceTime calls, or following recipes while cooking.

Experimenting with different hinge positions can help you discover practical ways to use the device without holding it constantly.

9. Customize StandBy Mode

StandBy mode is another feature that becomes more useful with the iPhone Duo's folding design.

Unlike traditional iPhones, the Duo can use StandBy while partially folded without requiring the phone to be connected to a charger.

You can turn it into a desk clock, photo display, or convenient place to view widgets.

The available display options include clock styles, calendar information, weather details, and photo collections.

Positioning the phone on your desk or bedside table can make important information accessible without picking it up.

Final Thoughts

The iPhone Duo offers more than a larger display. Its foldable design introduces new ways to multitask, take pictures, enjoy media, and use everyday applications.

Taking a few minutes to explore its Touch ID controls, camera features, display settings, and StandBy mode can make the device considerably more convenient.

If you've recently purchased Apple's first foldable iPhone, experimenting with these features is a great way to discover what makes the iPhone Duo different from traditional smartphones.
