5.2 mm open, 11.3 mm closed, and still thinner shut than the original iPhone, as Matt Talks Tech points out in a launch-day hands-on with the iPhone Duo. Of its five first impressions, the video leans hardest on the crease: other foldables show theirs at a glance, while the Duo's takes a deliberate camera angle to find, and the hinge doesn't register under a finger.
The 7.6-inch inner screen carries nano-texture, which the video credits with hiding the crease and cutting glare on video, with no blur the video could find. Netflix already moved its playback controls to the right edge for the Duo, good for right-handers and less so for left-handers. Split-screen multitasking takes a swipe up from the bottom, a slide to one side, and a second app pick, a routine Matt Talks Tech compares to losing the home button on the iPhone X and expects people to learn within a week. At launch, plenty of third-party apps didn't fill the screen yet, and the video gives developers three or four months to catch up.
The cameras get the bluntest verdict. The 48MP main and ultra wide handle everyday shots and 3x or 4x zoom, but at 10x next to an 18 Pro Max on a candle at night, the Duo's shot looks rough, and the video likens the 12MP front camera to the iPhone 16's. Smart Take and Kid Queue are the consolation: the first fires once the subject is in frame, the second brings Snoopy animations along for photos of kids.
That's the trade I'd judge the Duo on. It's a reading and watching device first, and iPhoners who zoom past 4x every week are still shopping for a Pro Max.
