The larger external displays are intended to allow users to obtain the information they want without having to open the device to use the larger internal display. As for the durability of the Quick View display on the Razr+, Nelson says that his “thumb cracked through the square display of the Motorola Razr+ like a fat polar bear on thin ice.”
The rest of the teardown shows Nelson taking apart the Razr+ and giving us a look at the inside of the device. He did note that the lack of dust inside the device revealed that the seals inside the phone, used to maintain the IP52 rating for the Razr+, were doing a good job. He also says that the motherboard has a “psychedelic sheen on top” that he compares to the parking lot of a grocery store after it rains.
