Some Samsung Galaxy Z Fold 4 users are reporting that their phones cannot fully open, and in some cases that their internal screens are breaking – and ironically the issue appears to be caused by a possible flaw with Samsung’s unique hinge design intended to protect the hinge mechanism.
Since the Samsung Galaxy Z Fold 2, Samsung’s foldables have featured a lining of tiny brushes inside the hinge mechanism for sweeping away dirt and debris when the phone is opened and closed to keep the mechanism free from obstructions.
