iPhone Duo First Impressions: From Weight to Crease

The iPhone Duo model with the case attached conveys a quite substantial weight. Especially when held in its folded state, the weight was significantly noticeable.

However, unfolding the device distributes the weight, providing an experience that feels relatively lighter. This is because the concentrated weight when folded spreads out over a larger surface area.

Beyond a certain middle angle of the hinge, it gives a sensation of opening with a 'click' sound.

The hinge supports a free-stop mode, allowing users to fix it at their desired angle, which enhances convenience in various usage environments.

Users had concerns about the iPhone Duo's screen design, which features one straight and one curved side. In reality, this asymmetrical design did not feel strange at all.

The internal UI processing effectively offsets this design disparity and does not negatively impact the user experience.

Night Sky is a color that resembles starlight in the night sky, with a hint of navy mixed into black.

Star White gives the impression of a blend of existing Starlight and White colors, with sides finished in a light champagne gold-toned cream ivory.

The main features of this case are its angle adjustment and stand function.

It is designed to stand upright even when the device is unfolded and features a structure that protects the hinge, complementing the weaknesses of foldable phones.

Compared to the Galaxy Fold, the iPhone Duo has a wider horizontal width when held in one hand. Users with small hands might find it somewhat uncomfortable to use the device with one hand.

When unfolded, the device gives the impression of using an iPad mini, offering an immersive experience with its wide screen.

It's only slightly thicker than the iPhone 18 Pro.

The thickness when the device is unfolded is not overly burdensome, suggesting it has decent portability as a foldable phone.

Nano-texture glass has the advantage of effectively reducing light reflection. However, users unfamiliar with this technology might perceive the screen as slightly hazy.

It feels less vibrant compared to a normal glossy screen, which can be a matter of personal preference.

During everyday scrolling, tactile interference is minimal, so it does not significantly impact the user experience.

The crease has a depth that is barely noticeable even when pressed firmly, making it almost imperceptible during general touch use.

Nano-texture glass has an excellent effect in reducing light reflection. However, there is concern that a similar issue might arise with the iPhone Duo, as previous experience with nano-texture on MacBooks showed fingerprints and oil easily remained, which was bothersome.

There is a possibility that fingerprint legibility may decrease when screen brightness is lowered, and it is also noted that the nano-texture coating on the folded part may accelerate wear due to the foldable structure.

The iPhone Duo's Under Display Camera (UDC) is almost invisible when viewed from above rather than head-on, enhancing visual completeness. However, due to the nature of the inner screen's UDC, resolution and clarity are somewhat reduced when using the front camera.

This is a current limitation of UDC technology, meaning users may have to compromise on image quality during video calls or selfie photos.

The iPhone Duo's StandBy mode causes the inner light to brighten and dim repeatedly when an alarm sounds, allowing it to be used as a wake-up light when placed beside the bed.

This allows for visual effects where water appears to collect on the screen.

Such 'obsessive' details maximize content immersion and provide users with a new visual experience.

The sound experience remains continuous, whether folded or unfolded.

The device calculates sound output in real-time during the unfolding process to achieve optimal spatial audio, providing users with seamless audio immersion.

It calculates how the video would appear when reflected and displays it on the bottom screen.

This detail provides users with visual entertainment, as if they are watching a mirrored reflection of the video.
