Thick rubber sidewalls and Gorilla Glass help protect the screen and internal components. The XP 3300 is military-certified to withstand extreme heat and cold, dust, humidity, drops, and other environmental conditions.
The phone is sturdy, not indestructible. Though 1.5 mm thick and able tot sustain drops up to 6.5 feet onto concrete, the strong Gorilla Glass screen didn't make it past our air-toss. The phone, however, still works, and there aren't any other scratches.
