Thicker UTG could raise production costs and complicate engineering, potentially impacting long-term durability (up to about 200,000 folds) and overall device pricing.

The reporting credits ZDNet Korea and notes related context from Wccftech, highlighting industry moves toward crease reduction and durability in foldables.

Analysts view the Z Fold 8 Wide as a testing ground for Samsung’s next-gen foldables, with UTG thickness as a potential differentiator that could influence competition with Apple.

The approach mirrors rumored iPhone Fold strategies, which explore thicker UTG and protective films to boost scratch resistance and deliver a cleaner display with fewer blemishes.

Samsung is developing a Wide Foldable smartphone using Ultra Thin Glass (UTG) thicker than the Galaxy Z Fold 8 to reduce crease visibility and boost durability, signaling a new approach to crease reduction.

The wider Fold aims to be more compact and reportedly less crease-prone than the traditional tall-form-factor Galaxy Z Fold 8 Ultra, and is positioned as a direct competitor to Apple’s iPhone Ultra.

Trade-offs include a thicker UTG layer that reduces creasing and improves drop resistance but may increase the risk of glass breakage when folded, affecting reliability for future models like the Galaxy Z Fold 9 in 2027.

UTG thickness is cited at 60 micrometers, about 30% thicker than the Z Fold 8’s 45 micrometers, with potential downsides including a more noticeable crease and higher risk from sharp interactions.

The report maps UTG thickness history across Galaxy Z Fold generations, noting 30 micrometers on Fold 6, and 45 micrometers on Special Edition and Fold 7, shaping expectations for Fold 8 variants.
