Galaxy Z Flip teardown reveals fine dust can still get into its hinge

The Galaxy Z Flip is Samsung’s second foldable phone, and the company has learned a lot over the past year and made notable improvements to its hinge and the screen protection. iFixit has now published a video teardown of the Galaxy Z Flip, giving us a detailed look at the phone’s internals.When Samsung unveiled the smartphone on February 11, it said that the new hinge in the Galaxy Z Flip has a fiber shield that is intended to stop dust from getting inside. The teardown video shows that the phone does really have brushes on the hinge, but they might not be able to stop much fine dust from getting inside the phone.The folded Galaxy Z Flip was dropped into a bag filled with purple-colored fine dust, and the dust was visible when the device was opened. It was most visible inside the hinge and near the loudspeaker grill. Although the phone isn’t rated for dust and water resistance, it was revealed that Samsung has coated the PCBs with a water-resistant layer, which should stop the phone from getting damaged from water splashes.
