According to a report from last week, Samsung will use ultra-thin glass (UTG) of different thicknesses on the upcoming Galaxy Z Fold8 (wide) and Galaxy Z Fold8 Ultra. Both foldables are expected to debut in July alongside the Galaxy Z Flip8.
Ultra-thin glass forms the top protective layer of a foldable phone’s flexible AMOLED display. It helps reduce the crease while protecting the screen from drops. According to the report, the Galaxy Z Fold8 (wide) will feature a 60μm-thick UTG.

The taller Galaxy Z Fold8 Ultra, on the other hand, is said to use a thinner 45μm UTG, matching the thickness found on the current Galaxy Z Fold7.

The thicker UTG on the Galaxy Z Fold8 (wide) will likely minimize the appearance of the display crease compared to the Ultra model. However, thicker UTG is generally less flexible and can be more susceptible to stress from repeated folding compared to a thinner glass layer.
If the thicker UTG performs as expected on the Galaxy Z Fold8 (wide), Samsung is reportedly considering using it on the Galaxy Z Fold8 Ultra’s successor in 2027.
