Samsung’s foldable screens fail in some early review models

Some test models of Samsung Electronics Co.’s new foldable phone have suffered defects after only days of use, casting a shadow over next week’s introduction of a $1,980 device meant to rejuvenate a flagging market and showcase the Asian company’s technology expertise.

Several publications, including Bloomberg News, outlined a bevy of problems with test versions of the device, which folds inward like a notebook. Bloomberg’s review unit experienced issues after a plastic protective layer was removed on Monday. By Tuesday night, a small tear had developed at the top of the hinge, where the gadget opens. Then the display failed to operate properly.

The Korean company suffered a black-eye with a previous major launch in 2016, when it recalled the Galaxy Note 7 after consumers reported issues with batteries that burst into flames.
