More than two weeks after Apple launched its first foldable smartphone, the iPhone Duo, major Apple applications continue to face screen optimization issues. Surprisingly, even Apple's own shopping app, the Apple Store, fails to fully utilize the iPhone Duo's expanded screen, leaving black bars on the sides. Apps from tech giants like Google and Microsoft also struggle to make the most of the larger display.

On November 6, MacRumors, a prominent U.S. tech news site, reported that while over 100,000 apps have been optimized for the iPhone Duo, many frequently used applications still lack support for the device's expansive screen.

The iPhone Duo hit the market on October 23. When unfolded, it boasts a 7.6-inch display, but apps that aren't optimized appear centered with black margins on either side, failing to utilize the full screen real estate.

The list of unoptimized apps includes Google's productivity suite (Docs, Sheets, and Slides), Microsoft Teams, PayPal, Starbucks, Uber Eats, and Wells Fargo. Surprisingly, even Apple's own Apple Store app lacks optimization for the larger screen.

These issues have been apparent since the device's launch. Tech publications like <em>CNET</em> and <em>Wired </em>highlighted the inability of some apps to use the entire expanded screen as a key area for improvement in their product reviews.

Multitasking capabilities on the large screen also have limitations. PhoneArena, a U.S. tech magazine, reports that while the iPhone Duo can display two apps side-by-side in landscape mode, the split-screen ratio is locked at 50-50.

When the device is rotated to portrait orientation, only the app on the right remains visible. Rotating back to landscape restores the previous split-screen view.

Apple maintains that app optimization efforts are progressing rapidly. Susan Prescott, Apple's vice president of worldwide developer relations, stated in a press release on November 6 that over 100,000 apps have been optimized for the iPhone Duo's screen, with thousands more being added daily.
