Several launch reviews found that unoptimized apps leave conspicuous black bars or narrow windows on the iPhone Duo’s 7.6-inch inner display, raising real questions about the value of Apple’s first foldable at $1,999.
Pre-orders opened October 16, 2026, and the device hit retail shelves October 23. For buyers still weighing the purchase, those review findings arrive at the worst possible moment.
A Real Problem, Documented Across Major Reviews
Three independent outlets found the same compatibility issue during testing, placing the problem well outside edge-case territory.
Wired found some apps displaying thick black side bars, effectively leaving a phone-sized application floating in the center of a tablet-sized screen. CNN identified Google Maps, Gmail, Call of Duty Mobile, and Uber as apps that had not been fully adapted to the Duo before launch.
Wirecutter similarly documented apps appearing as small phone-shaped windows or leaving a black bar along one side of the display. The finding surfaced consistently across independent testing from all three outlets.
Software, Not Hardware, Is the Culprit
Reviewers are clear that the display itself is not defective; the shortfall belongs to apps that have not yet been updated for the Duo’s wider screen.
According to CNN, apps require updated layouts and Apple’s latest development tools to correctly use the Duo’s wider screen and additional interface space. The issue is a software gap, not a display defect.
The situation was already shifting during the review period. Wired reported that Instagram, Threads, Slack, and Google’s app had begun adding improved layouts before the review concluded. That progress suggests the gap between hardware and software will narrow over time.
Buyer Reactions and the Value Question
Cancellation reports are circulating on social media, but no independently verified data establishes how widespread they are.
Social media reports indicate that some buyers cancelled pre-orders after seeing review coverage of the black bar problem. No independently verified data confirms the scale of those cancellations, and the claims should be treated as individual reactions rather than a confirmed pattern.
At $1,999, incomplete app optimization is not a minor footnote. CNN’s conclusion was direct: buyers without an urgent need for the larger screen may want to wait until developers have had more time to update their apps.
Reviewers were broadly positive about the hardware itself. Wired praised the hinge, the matte inner display, and battery life, reporting roughly 40% charge remaining after a full day of typical use.
Apple Enters a Market Samsung and Google Have Had Years to Shape
The app ecosystem challenge Apple faces now is one Android foldable makers encountered years earlier, with more time to resolve it.
CNN noted that many of the Duo’s core foldable concepts have existed on Android devices for years. That history has given Samsung and Google considerably more runway to support wide-screen app layouts.
This is Apple’s first foldable, and the app ecosystem challenge is a familiar one for the category. At $1,999, the practical question is whether the device is a finished product today or a very promising one by early 2027.
