iPhone Duo Reviews Highlight Touch ID Delays and Frustrating Unlocks

Apple's iPhone Duo introduces a different approach to authentication, replacing the familiar Face ID system with Touch ID. While the change may make sense for the device's design, early reviews suggest that some users could find unlocking the phone less convenient than they expected.

Several reviewers have highlighted a deliberate pause in the fingerprint unlocking process. Instead of moving straight to the Home Screen after recognizing a finger, the iPhone Duo briefly displays the Lock Screen, giving users a chance to check notifications before continuing.

Apple says this creates a more consistent experience with other Touch ID devices, including Macs and iPads. However, reviewers who are used to the near-instant response of Face ID say the extra step can make everyday interactions feel slower.

Why Touch ID Feels Slower on the iPhone Duo

Technology reviewer Marques Brownlee explained that Apple appears to have introduced an intentional delay into the Touch ID unlocking process. After placing a registered finger on the side button, users see the Lock Screen first. Keeping their finger in place allows the phone to proceed to the Home Screen.

The idea is to let people glance at notifications before opening the device. In practice, though, users who want immediate access may find the pause unnecessary.

Brownlee noted that the fingerprint reader itself does not necessarily appear to be slow at recognizing a finger. Instead, the extra step makes the overall process feel slower compared with Face ID. He also said he could not find a setting to disable the delay.

His workaround is straightforward: wake the iPhone Duo, swipe up, and then touch the fingerprint sensor. This approach allows him to unlock the phone more quickly without waiting through the initial pause.

Reviewers Share Their Frustrations With Touch ID

The concerns are not limited to one reviewer. Several publications and technology creators have described similar adjustment issues, although not everyone considers Touch ID a major problem.

Engadget reported that unlocking the iPhone Duo took longer than expected. Apple explained that the pause allows the device to wake up and show Lock Screen notifications, creating a more consistent interaction across products that use Touch ID.

Joanna Stern also described struggling with the unlocking process even after using the phone for a week and registering five fingers. Her experience highlights how difficult it can be to adjust to a different authentication method after years of relying on Face ID.

Meanwhile, Mrwhosetheboss compared the extra hold to a small inconvenience that users encounter repeatedly throughout the day. He also found that slightly greasy fingers or hands that had just been washed could cause problems. The placement of the sensor was another concern, as he found it more comfortable to use the phone in landscape orientation.

These experiences suggest that the main issue may not be fingerprint recognition alone. The timing, sensor placement, and need to position a registered finger correctly can all affect how natural unlocking feels.

Accidental Touches and Apple Pay Create More Challenges

Some reviewers have also raised concerns about accidental interactions. PetaPixel described receiving frequent haptic error alerts when touching or moving the phone, making the experience feel more distracting than expected.

Authentication can also feel different when using Apple Pay. With Face ID, users can generally look at their phone to authenticate supported payments. Touch ID requires physical contact with the registered finger, which may take some getting used to for people switching from a Face ID-equipped iPhone.

Cold weather introduces another practical limitation. As Gizmodo pointed out, users wearing ordinary winter gloves may need to remove them to unlock the device with the fingerprint sensor.

Individually, these issues may seem minor. However, unlocking a phone, checking notifications, and approving payments are actions people perform frequently. Even small delays can become noticeable when repeated throughout the day.

Can an Apple Watch Make Unlocking Easier?

One alternative is to use an Apple Watch to unlock the iPhone Duo. According to PetaPixel, this method was faster than relying on Touch ID and reduced much of the friction associated with the fingerprint sensor.

For users who already wear an Apple Watch, this could be a practical workaround. It offers another way to access the phone without repeatedly placing a finger on the side button.

Brian Tong also suggested that users would appreciate having an Apple Watch when using the iPhone Duo. However, this option may not appeal to everyone, particularly those who do not own a watch or prefer to authenticate directly on their phone.

The available workarounds can help, but they do not change the underlying design choice. People moving from a Face ID-equipped iPhone will still need to adapt to a different unlocking routine.

What the Touch ID Experience Means for iPhone Duo Buyers

The mixed reviews show that Touch ID is not necessarily unusable, but it may require an adjustment period. The Verge reported that a week was enough to become accustomed to the system and described the experience as mostly painless once the new routine became familiar.

Similarly, 9to5Mac acknowledged that Touch ID could be the iPhone Duo's biggest tradeoff while noting that the sensor worked quickly and reliably.

For potential buyers, the important distinction is between fingerprint recognition and the complete unlocking experience. A sensor can recognize a finger reliably while the extra steps still make the phone feel less responsive.

Anyone considering the iPhone Duo should think about how they normally unlock their phone, whether they regularly use Apple Pay, and how often they need to authenticate in situations where touching the sensor may be inconvenient.

Switching Phones? Make Your Data Transfer Easier

Changing to a new iPhone involves more than getting used to its authentication system. You may also need to move contacts, photos, videos, and documents from your existing device.

Smart Transfer can help move supported files between compatible phones, making it easier to keep important content accessible while setting up a replacement device. If you're upgrading to the iPhone Duo, organizing your files and checking your backup options beforehand can make the transition smoother.

A contact transfer process can help you prepare your address book, while contacts files transfer options may be useful when moving supported contact information and other files between compatible devices. For moving files over a wireless connection, wifi files sharing can also be a convenient option when supported by your devices and transfer method. Keep in mind that app data, passwords, Apple Pay information, and certain protected content may require Apple's own migration or backup tools.

Final Thoughts

The iPhone Duo's move to Touch ID has become one of the most discussed compromises in early reviews. Some users may appreciate the chance to check notifications before unlocking, while others will miss the speed and convenience of Face ID.

The reported delay, occasional recognition difficulties, accidental haptic alerts, and changes to Apple Pay authentication could take time to get used to. Still, some reviewers found that Touch ID became easier to live with after several days.

Ultimately, whether the change feels frustrating will depend on individual habits and expectations. For people who value quick, hands-free authentication, the iPhone Duo may require a noticeable adjustment. Those comfortable with fingerprint unlocking may find the transition less significant.
