Samsung ‘Wide Fold’ Surfaces in Early One UI 9 Leak, Pointing to Wider Book-Style Design

An instructional animation in early One UI 9 test builds points to active software preparation for a wider foldable format.

Overview

  • An animation found in an early One UI 9 (Android 17) test build references a foldable codenamed H8 and shows a noticeably wider cover screen with a swipe-up notification demo before the device opens.
  • Reporting describes a more square inner display targeted at roughly a 4:3 aspect ratio, indicating a shift toward productivity- and content-friendly proportions.
  • Outlets suggest the device could debut alongside the Galaxy Z Fold 8 and Galaxy Z Flip 8 this summer, though the animation does not confirm hardware or launch plans.
  • Coverage cites tipster AssembleDebug’s discovery via Android Authority, with Android Central adding that testing and a potential launch are being explored for the U.S., Korea, China, Canada, and other regions.
  • The Indian Express relays unconfirmed details including a possible model number (SM-F971U), a reported sales target of at least 1 million units, and conflicting claims on the inner display size compared with the Z Fold 7.
