Samsung Galaxy S4 is not waterproof. Some of its special features include sharing music and images using Group Play, controlling the unit without touching the screen but using Air Gesture and recording sound with photo shots using Sound and Shot.
Among the Samsung Galaxy S4 collection, only Samsung Galaxy S4 Active is waterproof. It is protected against liquid splashes and can even be submerged in water for 30 minutes to a depth of one meter. It can be used to shoot images and capture videos underwater with optimised clarity using the Aqua Mode. To snap a picture underwater, a volume key is used instead of the touchscreen.
