Later this week will see Samsung announce the next generation of Galaxy Foldables, and it's already been confirmed that these phones will feature a crease-free "Flex Titanium" display for the Galaxy Z Fold 8 and Galaxy Z Fold 8 Ultra.
This essentially means that Samsung has added extra layers to the display, including a titanium-alloy film and a titanium base plate, which works to reduce crease visibility along the phone.
