25 Things to Try First on Your New iPhone Duo
From rear-camera selfies and tabletop video to split-screen planning, here are 25 useful and entertaining ways to learn what makes iPhone Duo different.

Here are 25 experiments that teach the hardware without turning setup day into homework.
Start with the fold
- Set up on the outer display. Notice which essential controls remain comfortable one-handed.
- Open the same app without closing it. Check whether your place, draft, or playback position remains intact.
- Read a long article fully open. Try portrait and landscape arrangements before choosing a favorite.
- Prop it in tabletop mode. Set a timer and see how the controls divide across the fold.
- Try tent mode on a desk. Use it as a glanceable clock or media controller where supported.
The hinge is not a party trick by itself. Its value appears when an app preserves context while the posture changes.
Explore the cameras
- Take a rear-camera selfie with the outer preview. You get the quality of the main camera with visible framing.
- Ask a friend to pose using Duo Preview. Let them adjust before you press the shutter.
- Try Smart Take with a small group. Compare the automatic timing with a conventional timer.
- Use Kid Cue with family—with permission. The outward animation can help catch attention, but respect parents and privacy.
- Record a hands-free cooking clip. Tabletop posture replaces a small tripod for simple angles.
- Make a Duo FaceTime call. Explore how the outer display changes a shared conversation.

Make the large display useful
- Plan a trip with a map and notes side by side. Keep addresses visible while building an itinerary.
- Compare two products without tab switching. Use split view to keep specifications and reviews together.
- Watch a tutorial beside the app you are learning. Pause often and recreate each step.
- Edit a photo with a larger preview. Keep tools from covering the subject.
- Read and take notes in one workspace. Our reading and notes workflow explains a practical setup.
- Open a long email beside your calendar. Confirm dates without losing the draft.
- Try a controller-supported game. Decide whether the expanded view is worth the additional battery use.
Learn your battery habits
- Spend one morning mostly closed. The outer display may handle more than you expect.
- Spend one evening mostly open. Compare comfort and remaining battery.
- Check battery use after gaming or navigation. The inner display changes your normal power pattern.
- Charge while the phone is partially open. Make sure your stand, cable, and case remain stable and ventilated.
Our inner-versus-outer battery guide helps interpret the results.
Personalize for real life
- Increase text size and test both displays. Choose readability over fitting more cards.
- Arrange outer-display essentials first. Prioritize camera, messages, maps, wallet, and audio controls.
- Create one foldable-specific routine. It could be a recipe station, bedside clock, travel dashboard, or reading notebook.
What not to do on day one
Do not peel the factory inner-screen layer, force the hinge, or assume every case protects the same areas. Read the inner screen protector care guide before cleaning or adding accessories.
Also avoid judging every app by whether it fills the display. A thoughtful single-column experience can be better than a stretched interface. Look for preserved state, sensible controls, and useful use of extra space.
The best first week with iPhone Duo is not about completing every trick. It is about discovering which two or three new behaviors genuinely remove friction from your day.
