Pixel 10 Pro Fold could be first foldable with this feature topping the Galaxy Z Fold 7 and Flip 7
As a result, most foldables used to have Ingress Protection ratings of IPX8. The “X” means that those devices were not rated for their protection from dust and other small particles. The 8 means that the device can be submerged in clear water up to nearly five feet for as long as 30 minutes and escape unscathed.

The Pixel 10 Pro Fold will be the first foldable to have an Ingress Protection rating equal to the IP68 rating that you might find on a high-end smartphone. Google was able to achieve this by making the hinge on the foldable thinner which will also make the device more comfortable to hold. While the hinge will be thinner, the bezel will be stretched out allowing the cover display to rise from 6.3-inches on the Pixel 9 Pro Fold to 6.4-inches on the Pixel 10 Pro Fold.
