iPhone Duo Review: Why Reviewers Miss Face ID

The iPhone Duo marks Apple’s most significant iPhone design shift in years. Rather than refining the familiar slab-shaped phone, Apple introduces a foldable device that works in a compact state and opens into a larger workspace.

Early reviews praise the hinge, build quality and potential of the foldable design. However, reviewers also identify familiar usability compromises. The most repeated complaint is the absence of Face ID.

That criticism matters because Face ID is more than a technical specification. It is part of the everyday iPhone experience, helping users unlock the phone, authorize purchases and access apps with minimal effort. When that interaction disappears, the change becomes noticeable several times a day.

The emerging iPhone Duo review consensus is balanced: Apple has created an ambitious and polished foldable, but the software can feel messy and authentication is less seamless without Face ID.

What Reviewers Like About the iPhone Duo

An Impressive Hinge

A foldable phone depends heavily on its hinge. It must feel precise, remain stable during use and withstand repeated movement without making the device seem fragile.

The hinge gives the phone a sense of purpose and refinement. It also helps connect the folded and unfolded modes into one cohesive product. However, strong hardware cannot resolve software friction or authentication issues.

A Meaningful New Form Factor

The appeal of a foldable iPhone goes beyond novelty. The compact mode is convenient when portability matters, while the expanded mode provides more room for reading, video, multitasking and work.

The design could attract users who want more screen flexibility without leaving Apple’s ecosystem. Its value depends on whether iOS responds naturally to the changing device states. The hardware creates the opportunity; the software determines whether it feels useful.

Strong Overall Quality

That distinction is important. The iPhone Duo is not a failure. Its hardware quality and overall polish may justify the compromises for buyers who want Apple’s foldable direction. The phone can be impressive and inconvenient at the same time.

Why Reviewers Miss Face ID

Face ID Is Part of Everyday iPhone Use

Face ID works in the background. Users rely on it to unlock the phone, authenticate apps and authorize purchases without deliberately entering a passcode or positioning a finger.

Removing such a familiar feature feels more disruptive than removing a function users rarely notice. That explains why the iPhone Duo Face ID criticism appears repeatedly in early coverage. MacRumors reports that reviewers particularly miss Face ID on the device. Source 1

The criticism does not necessarily mean that the iPhone Duo lacks secure authentication. It means the replacement does not deliver the same familiar, effortless experience.

Foldable Use Makes Authentication More Noticeable

A foldable can be unlocked while closed, opened after authentication, placed on a desk or moved between screens during a task. Authentication therefore needs to work naturally in every position.

The iPhone Duo introduces more movement and more hand positions than a conventional iPhone. Any additional step becomes noticeable because users are already adapting to the changing form factor.

The available review summaries do not provide enough detail to identify every aspect of the replacement authentication system. The broader point is clear: authentication must fit the foldable experience and remain reliable whether the phone is closed, open, stationary or in motion.

A Recurring Usability Problem

Repeated criticism points to a routine ownership issue rather than an isolated reviewer preference. Face ID affects frequent tasks, so small inconveniences accumulate throughout the day.

Users who rarely rely on Face ID may consider the change minor. Those who use it for payments and app access may see it as a serious drawback.

Software Creates Additional Friction

A Messy Experience

Software is especially important on a foldable because the device changes its physical layout. The operating system must manage transitions between states without forcing users to think about the underlying mechanics.

The available summary does not identify specific bugs or interface elements. The central criticism concerns polish, consistency and workflows that do not feel fully adapted to the form factor.

Polished but Imperfect

The review pattern supports a measured verdict. The hardware earns praise, while usability creates reservations. The device remains compelling despite its flaws, but its strengths do not erase them.

Is the iPhone Duo Successful?

The iPhone Duo has several qualities that support a positive verdict:

• Its hinge demonstrates credible hardware execution.
• Its foldable format represents a meaningful new direction for the iPhone.
• Its overall quality remains strong despite significant compromises.
• Its design reflects a broader shift in smartphone form factors.

The counterargument is equally clear. Reviewers miss Face ID, MacStories criticizes the software experience and Tom’s Guide identifies recurring flaws across its review roundup. Source 3 Source 7

The strongest conclusion is that the iPhone Duo is an ambitious, polished foldable with clear usability trade-offs. It is neither a complete failure nor an unqualified success.

What Apple Should Improve

Restore or Replace Face ID

Apple should restore Face ID or provide an equally effortless biometric system. Authentication should work naturally in every device position and remain consistent across unlocking, payments and app access.

Refine Foldable-Specific Software

Apple should improve transitions between folded and unfolded states, reduce unnecessary steps and remove confusing interactions. The interface should feel designed for a foldable rather than adapted from a conventional phone.

Preserve the Hardware Strengths

Future versions should retain the iPhone Duo’s impressive hinge and strong build quality. Apple must continue balancing durability, thinness and usability without allowing one goal to undermine the others.

Final Verdict

The iPhone Duo shows meaningful promise. Its hinge is impressive, its foldable design points toward a possible future for the iPhone and its overall quality remains strong. However, reviewers also identify messy software and repeatedly say they miss Face ID.

The best iPhone Duo review verdict is measured: this is an important but imperfect first-generation foldable. Choose it for the foldable design and hardware innovation, not for the most familiar iPhone experience.

FAQ

Does the iPhone Duo have Face ID?

The supplied review summaries indicate that reviewers broadly note missing or unavailable Face ID functionality. They do not provide enough detail to confirm the exact authentication hardware or replacement method. Source 1

Why do reviewers miss Face ID?

Face ID is a familiar, low-effort part of daily iPhone use. Its absence becomes more noticeable when users unlock and authenticate while moving between folded and unfolded positions.

Is the iPhone Duo’s hinge impressive?

Yes. MacStories specifically highlights the hinge as one of the iPhone Duo’s hardware strengths. Source 3 It strengthens the phone’s credibility as a foldable but does not eliminate software or authentication compromises.

Is the iPhone Duo worth buying?

It may suit buyers who prioritize a foldable iPhone and accept trade-offs. Buyers who rely heavily on Face ID or want the most familiar iPhone experience may prefer a conventional model.

Is the iPhone Duo the future of the iPhone?

9to5Mac presents foldable design as a significant direction for smartphones. Source 9 The iPhone Duo shows that Apple’s foldable approach has potential, but future versions still need software and authentication improvements.
