iPhone Duo hidden tricks: 7 features Apple never told you about

Apple has released the iPhone Duo, its first foldable smartphone, featuring several undocumented hidden tricks that enhance productivity, privacy, and entertainment beyond its standard multitasking capabilities. The device allows users to create app pairs for one-gesture split-screen launching, offers an automatic privacy mode when closed, and provides two keyboard layouts—split for thumbs or full-screen for long texts. It also includes display adjustments for unoptimized apps, a hidden Control Center access via status bar icons, and a dual preview mode for selfies. Additional features include using the partially folded hinge as a stand for clocks or video calls, and strong emulator support with virtual controls on one half of the screen for a portable console experience.
