Samsung starts mass production of Galaxy Z Fold 4 and Galaxy Z Flip 4 components.

Samsung reportedly expects to ship 10 million units combined of the Galaxy Z Fold 4 and the Galaxy Z Flip 4 this year. The latter is a pocketable device that features a small outer display for messages and notifications. Whenever you need to make a call, open an app, or want to play a game, you flip the screen open to reveal a large smartphone-sized display (6.7-inches on the Galaxy Z Flip 3).
