Apple Debuts iPhone Duo as Samsung Defends Z Fold8 Corner ‘Softness’

Apple pitched an engineering-first foldable that aims to reduce the crease while early supply limits and Samsung’s strong Z8 demand are reshaping the market.

Overview

  • Apple unveiled the iPhone Duo on Wednesday and said the device uses a multi-layer, nanostructured display, a hinge made of more than 100 parts, and a screen assembly it describes as about 40% more rigid to make the fold visually flatter and less tactilely creased.
  • Samsung reported cumulative seven-day pre-sales of about 1.44 million Galaxy Z Flip8 and Z Fold8 family units in Korea and KTOA data showed a marked rise in number-porting that one industry official tied to Z8 demand and an increased share of former iPhone users switching to Samsung.
  • Users and reviewers reported a slight sinking or softer feel at the inner-screen corners of some Z Fold8 phones and Samsung said the design allows small corner deformation on purpose to buffer against particles and prevent screen damage rather than signaling a manufacturing fault.
  • Multiple reports say Apple’s initial foldable output will be constrained, with resale and reservation services charging elevated fees, and Rongqi Technology has confirmed it took part in thermal VC testing for Apple’s foldable validation.
  • Apple also received a granted U.S. patent for a ‘stretchable display’ design (US-12730478-B2) that uses sealed rigid pixel islands with flexible interconnects, signaling the company is exploring rollable and alternative form factors beyond conventional folding.
