Samsung’s first foldable smartphone will go on sale in September after problems with the device delayed its initial release.
Improvements include extending a protective layer to make it clear it is not meant to be removed, as well as strengthening the hinge area with new protection caps.
One explanation for the broken screens appears to have been that some reviewers removed a film which they thought was a typical protective layer that came with the phone when first bought.
The defects with the device proved a source of embarrassment for Samsung which has seen declining smartphone sales and faces growing competition from rivals including China’s Huawei.
Huawei became the second largest smartphone seller in the world last year and also plans to launch its folding smartphone in September.
