It's been a week since the iPhone Duo was released, and MacRumors videographer Dan Barbera wanted to revisit his review since he's been able to use the Duo for a longer stretch of time.Subscribe to the MacRumors YouTube channel for more videos.You've probably seen images of iPhone Duos with a bright white line running across one side of the inner display. There is a defect affecting some users, but Apple says it's a problem limited to a small number of units.None of us at MacRumors have had a display crack, and we've seen some AI photos floating around, so it's hard to tell just how many people are actually having problems. iPhone Duos with the hinge issue that causes the display to crack seem to get damaged shortly after purchase, so if you've had an ‌iPhone Duo‌ for the last week and it's still fine, it's not likely to have this defect.The outer display is small, but Dan finds it useful for checking notifications, replying to messages, and scrolling through apps and websites. He unfolds it for multitasking or longer messages, and is a fan of using the ‌iPhone Duo‌ unfolded in portrait mode for watching videos and using an app at the same time.He finds the Touch ID fingerprint sensor easy to find, and says Apple Watch unlock is similar to Face ID. The cameras are just okay, and someone who zooms in a lot is probably going to miss having a telephoto lens.Battery life is between an iPhone 18 Pro and a Pro Max, and for most people, it's likely going to last a full day. Not all apps have been updated for the Duo layout yet, but it's getting better. There's an extension called Wider that extends the Safari window to the edges of the ‌iPhone Duo‌'s outer display, and it's a big improvement. We may see other accommodations in the coming months as developers and users get used to the new layout.Dan says the ‌iPhone Duo‌ is the most excited he's been about an iPhone in a long time, and he plans to keep using it even though he misses having a telephoto lens.Did you get an ‌iPhone Duo‌? What do you think now that you're a week into using it?
