Apple's iPhone Duo foldable introduces camera features leveraging its dual-display design, including Smart Take for group photos, Kid Cue animations, and Duo Preview for live subject feedback. The device features a 48MP dual-camera system with 4K Dolby Vision video and AI-powered smart focus tracking, but lacks telephoto, ProRAW, and advanced pro features found in iPhone 18 Pro models.
Apple's new iPhone 18 Pro and Pro Max ($1,199–$1,299) share the same A20 Pro chip as the foldable iPhone Duo ($1,999), but the Duo sacrifices camera quality and features like Face ID for its unique 7.6-inch folding display, making it best suited for users who prioritize screen real estate over photography capabilities.
Apple's iPhone 18 Pro pre-orders show lukewarm demand with 3-4 week wait times only for select high-storage models, while most configurations are immediately available. Analyst Jeff Pu attributes softer-than-expected demand to limited spec upgrades and higher pricing, and has trimmed production estimates for both the Pro lineup and the upcoming iPhone Duo foldable.
Apple's iPhone Duo includes a hidden "Shift Left Edge" display setting that adds a black border to the left side of the screen to accommodate cases that cover that area while preserving iOS back swipe functionality. The setting was discovered by blogger Nicolas Lellouche in the Display & Brightness menu, and the device launches October 23.
The iPhone Duo, Apple's first foldable iPhone, lacks 10 features found on the iPhone 18 Pro models, including a dedicated telephoto camera, variable aperture, higher-resolution front camera, Action button, Face ID, LiDAR Scanner, and advanced camera features like ProRAW and spatial video. The iPhone 18 Pro launches September 18, while the iPhone Duo releases October 23.
