Here’s why foldable phone displays can be scratched so easily
As exciting as foldable devices might be, the hard truth right now is that smartphone makers are in no position to manufacture glass that can bend over and over without breaking. The Galaxy Fold, Huawei Mate X, Motorola Razr, and Galaxy Z Flip feature fragile screens that break easier than traditional smartphone displays.
The Z Flip is causing a stir, as it happens to be the world’s only foldable phone to feature a foldable screen made of glass rather than a transparent polymer. Yet, durability tests suggest that Samsung may have been generous with its Ultra Thin Glass (UTG) claims. It turns out that the Galaxy Z Flip does have a glass screen, but that display is covered by a plastic film that’s meant to protect the glass. And such contraptions won’t go away anytime soon.
