Because of the resilient construction, this phone is perfect for those with an active life who might get involved in off-road pursuits like dirt biking, mountain climbing or riding the river rapids. The 4H hardness of the anti-scratch screen means it is possible to avoid damage even when dropped from the pocket onto concrete or rocks.
