As of 2015, Samsung does not have any waterproof phones, but offers four models of water-resistant smartphones: the Galaxy S6 Active, Galaxy S5 series, Galaxy S4 Active and Xcover 3. The Samsung Rugby 4 flip phone is also water-resistant.
Electronics are rated for dust and water resistance using a two-digit Ingress Protection Code, or IP Code. The first digit indicates dust resistance on a scale from one to six. The second digit indicates resistance to water on a scale from one to nine.
Samsung's water-resistant cellphones are rated at IP67, meaning that they are fully sealed against dust intrusion and are water resistant for 30 minutes when submerged in up to a meter of water.
