Samsung unveils foldable phone

Samsung Electronics on Tuesday unveiled a square-shaped foldable smartphone, its second try at a novel technology that the Korean cell phone maker hopes will set it apart from rivals Apple Inc and Huawei. The foldable-glass Galaxy Z Flip, which looks like a large makeup compact folded up and expands to look like most smartphones, will come in purple, gold and black, executives said in San Francisco.

Last year's Galaxy Fold, a larger unit that folds like a book and was largely panned on its debut, had a plastic screen. The Z Flip phone, starting at $1,380 will be available starting Friday.
