Apple is testing a square, clamshell-style foldable iPhone internally, according to Bloomberg's Mark Gurman. The device, unofficially called "iPhone Flip," would compete directly with Samsung's Galaxy Z Flip7 and Motorola's modern Razr lineup.
The clamshell iPhone would follow Apple's first foldable device, which is expected to launch in September 2026. That initial model will open like a book with a 7.7-inch inner display and 5.3-inch outer screen, according to The Information, similar to Samsung's Galaxy Z Fold series.
Apple's engineering teams are currently evaluating the square foldable design inside company labs. This marks the second time Apple has explored clamshell prototypes, following earlier investigations in 2024 that resulted in book-style foldables taking priority.
The potential iPhone Flip focuses on portability rather than screen size. It would fold into a compact square shape for pocket storage, then expand to standard smartphone dimensions for daily use. This approach contrasts with the larger, tablet-like experience of book-style foldables like the upcoming iPhone Fold.
Apple's strategy depends on market reception to its first foldable iPhone. Company executives believe strong initial sales could create demand for multiple foldable form factors, mirroring the expansion of traditional iPhones into Mini, Plus, and Pro variants over recent years.
No release timeline exists for the clamshell iPhone. Gurman emphasized the project remains in early development stages and "is far from guaranteed to reach the market." Apple's immediate focus remains the September launch of its book-style foldable iPhone.
If greenlit, the iPhone Flip would enter a competitive segment where Samsung dominates with its Galaxy Z Flip series. Motorola, Honor, and Xiaomi also offer clamshell foldables across various price points, with Samsung recently adding a more affordable Fan Edition model to broaden accessibility.
The clamshell design offers practical advantages beyond compact storage. Folding screens face less daily exposure when protected inside the closed device, potentially extending display longevity. This could appeal to users who prioritize durability alongside portability.
Apple's exploration of multiple foldable form factors signals long-term commitment to the technology. The company appears to be testing how far foldable designs can integrate into its ecosystem, potentially creating distinct product categories beyond traditional smartphones.
Industry analysts note Apple's cautious approach contrasts with competitors who launched multiple foldable models simultaneously. The staged rollout allows Apple to gauge consumer response before committing to additional form factors, reducing financial risk in an unproven market segment.
Market conditions will ultimately determine the clamshell iPhone's fate. With foldable smartphone sales growing but still representing a small fraction of overall smartphone shipments, Apple's measured expansion strategy reflects both ambition and pragmatism in a developing product category.
