Both the Samsung Galaxy Z Fold 5 and Samsung Galaxy Z Flip 5 could be getting a toughened hinge, says leaker chunvn8888, who claims Samsung's foldables could be rated IP58 for the first time.
The Galaxy Z Fold 4 and Galaxy Z Flip 4 are rated IPX8, meaning they're as water resistant as other flagship phones, but have no guaranteed protection against small particles entering the device, and potentially damaging the inner components. IP58 means instead that, as well as being waterproof up to 1 meter, the phones would be "dust protected", meaning while dust could still enter the phone, it, in theory, wouldn't cause any problems for using the device.
