Samsung Electronics has launched a new foldable phone and several new 5G devices. Samsung announced the telephone and other products during an event Tuesday in San Francisco, California. The new phone is called the Galaxy Z Flip. It goes on sale February 14 and has a starting price of $1,380. When open, the Galaxy Z Flip is similar in shape and size to most smartphones. When closed, the phone collapses down to half its size, in the shape of a square. The Galaxy Z Flip is the company's second foldable phone. Samsung launched its first model, the Galaxy Fold, last year. That phone closes up over the middle and opens up to the size of a small tablet. Technology critics have noted design problems with the Galaxy Fold, which also experienced delays in production.
