Although the market for foldable devices is slowly but surely growing, the one concern that is still there is durability for many people. Granted, the Galaxy Z Flip brought Samsung's take on Ultra-Thin Glass (UTG) and offered a better hinge. The Galaxy Z Fold 2 was built upon the same formula and offered some more refinements, but the one thing missing from the foldable devices so far is a proper IP rating. However, the latest tip suggests that both the Galaxy Z Fold 3 and Galaxy Z Flip 3 will ship with an official IP rating, which is only going to make these phones a better case for anyone looking for improved durability.

The report reveals that both of the upcoming foldable devices from Samsung will feature IP ratings, but it is important to know that we are not sure what the rating will be. It might not be possible to give these phones the same IP68 rating that the Galaxy S21 series ship with, but anything close to that would be more than welcomed.
