- Samsung’s new foldable phones offer an IP48 rating, but they’re still not dust-resistant.
- The upgraded rating means they’re only protected against objects 1mm in size or larger, while dust is much smaller than that.
- This is still a step in the right direction for ingress protection on Galaxy foldables.
Samsung finally unveiled the Galaxy Z Fold 6 and Galaxy Z Flip 6 yesterday, and one of the most prominent upgrades is the switch from an IPX8 rating to an IP48 rating. This new rating doesn’t mean the foldables are dust-resistant, though.
The first digit in an IP rating corresponds to ingress protection against solid objects. However, the commission behind the IP rating system notes that the “4” in an IP48 rating means the device is only protected against objects 1mm in size and greater (e.g. wires). Needless to say, dust is much smaller than that.
