IP stands for Ingress Protection and it’s a rating used to define how effective an electronic device is at keeping foreign elements away from the internal components. The first digit after IP is used to determine the device’s protection against dust and other foreign particles, while the second digit relates to water resistance.
With that being said, an IP67 dust and water resistance rating for the Galaxy means that these phones are entirely dust proof. 6 is the highest rating for dust resistance and it provides full protection.
The water resistance scale is wider, going from 0 (no protection) all the way up to 9 (full protection against high-pressure, high-temperature jet sprays). With a water resistance rating of 7, the Galaxy should be protected against water damage when immersed in up to 1 meter of water for up to 30 minutes.
Comparatively, Samsung’s flagships (and a few older Galaxy A phones) come with an IP68 rating. It means that they offer the same protection against dust but they have a higher degree of water resistance at greater depths of up to 1.5 meters.
