The design of the S5 evolves upon the design of the S4. It features a rounded, polycarbonate chassis carrying a “modern glam” look, faux metal trim and a removable rear cover. Unlike past models, the S5’s rear cover uses a higher quality soft plastic and is dimpled to improve grip. The S5 is IP67 certified for dust and water resistance. As such, the phone is able to be submerged in water up to 1 meter (3.3 ft) for up to 30 minutes. The S5’s Micro-USB 3.0 port uses a removable cover.
