5 Big Problems Users Are Already Having With The iPhone Duo

Key Points:

• Apple's first foldable iPhone, the iPhone Duo, has faced early issues including inner display cracking, unoptimized apps, and overheating during certain tasks, despite its $1,999 price tag and innovative design.
• Some users reported hearing a crunch sound from the hinge followed by cracks in the inner display near the crease, with iFixit suggesting possible mechanical stress or hinge misalignment as causes; Apple acknowledged the issue but considers it limited to a small number of units.
• Many commonly used apps remain unoptimized for the iPhone Duo’s unique foldable display, resulting in black bars and poor user experience, and even Apple's own apps like Safari have layout issues on the device.
• Despite a revamped vapor chamber cooling system designed to manage heat from the powerful A20 Pro chip, users report the iPhone Duo becomes uncomfortably hot during light use, a phenomenon also seen in other recent iPhone models.
• The iPhone Duo’s camera system is criticized for lacking a telephoto lens and having lower-quality sensors compared to recent iPhone Pro models, while the new iOS 27.2 software still shows bugs and UI glitches specific to the foldable design, expected to be addressed in future updates.
