The Galaxy Z Flip ended up being slightly more durable than the original Galaxy Fold, mainly due to the use of Samsung’s Ultra-Thin Glass or UTG technology. Looking at this improvement, Samsung will naturally take the things that made the Galaxy Z Flip special and when it comes to the launch of the Galaxy Z Flip 2. Though there’s no word when the successor will materialize, a fresh specifications leak reveals promising information about the upcoming model.

New information from the tipster Chun reveals that the Galaxy Z Flip 2 will feature a new UTG and a bigger outer display, but it’s not clear if the material will be glass, plastic, or something in between. There are reports of Samsung working closely with Corning to develop a special type of glass specifically designed for foldable smartphones so it’s possible we hear some positive news in the future.
