The rear panel of the phone is responsible for keeping all of the device's hardware safe and secure. It is secured by eight screws, and is accessible by first removing the back cover and battery. If the rear panel is damaged, it should be removed and replaced as a damaged panel can lead to damage of other internal hardware. Required tools for replacement include a torque screwdriver, a spudger, tweezers, and a prying tool. ''Note: after removing the eight torque screws, the rear panel must be pried off using a spudger and a prying tool. Use caution not to damage the device as it takes force to remove the rear panel. ''
