Otterbox Symmetry - Protective iPhone Case The combination of two materials makes the Symmetry series one of the thinnest, safest smartphone case series in its class. NO SCRATCHES Rest assured and slide your phone on your desk, table or other flat surface. With raised rubber edges around the screen and camera, the CRYSTAL MATTER case protects them from scratches. ANTIBACTERIAL TECHNOLOGY Think of all the surfaces you touch throughout the day. Now think about how many times you touch your phone. We transfer germs from shopping cart handles, doorknobs and bathrooms to our phone every time we touch it. We put our phone to our cheek while talking or pass it to someone else who returns it to us with new germs. The Gear4 case is equipped with antibacterial technology that inhibits the growth of odour-causing bacteria by destroying 99.9% of surface bacteria, providing protection against degradation by microorganisms. DROP+ Wireless Charging Compatibility DROP+ is legendary Otterbox protection that you can rely on in all conditions. Otterbox has created its own standard confirming the impact resistance of devices in cases. Most protective cases are certified to the MIL-STD-810G 516.6 military standard. Otterbox has created its own DROP+ standard, which, depending on the series, exceeds the MIL-STD protection level by up to 5 times.
