An early review says that Samsung's Galaxy Fold is still highly fragile
In April 2019, after early reviewers reported that that the foldable screen in their Galaxy Fold devices broke down after a day or so, Samsung decided to delay the release of its foldable smartphone, the Galaxy Fold. Samsung started shipping the re-designed and improved Galaxy Fold in Korea on September 6.
Samsung took three months to re-design and fix all the issues in the Fold smartphone, it updated the design and upgraded the construction to better protect the device from external particles. An early review now says that the Galaxy Fold may be improved, but it is still not durable enough.
