Media reviews suggest iPhone Duo's Touch ID may frustrate users accustomed to Face ID. Reviewers found Touch ID slow to unlock due to an intentional delay, pausing on the Lock Screen before proceeding to the Home Screen. This pause is designed to allow notification viewing but feels jarring to those expecting instant unlocks. Marques Brownlee reported that even with an intentional delay, the fingerprint reader itself isn't slow, but the unlock process feels sluggish. Many reviewers expressed missing the seamlessness of Face ID, with some fumbling unlocks even after a week of use. Apple states the pause provides a consistent experience with other Touch ID devices and allows Lock Screen notifications to appear. Some found Touch ID problematic with wet or greasy fingers and only comfortable in landscape mode. Accidental presses on the sensor can also trigger a haptic error buzz, which some experienced frequently. Unlocking with an Apple Watch is offered as an alternative and was found to be faster than Touch ID by some. Using Touch ID felt like a step backward for unlocking and for authenticating payments like Apple Pay. While some reviewers eventually got used to Touch ID, it's highlighted as a significant tradeoff for the iPhone Duo.
