There’s no question that the Motorola RAZR is today’s hottest 4G LTE phone, and if you wonder how Motorola managed to build a phone that is just about half of the thickness of the first generation LTE phones, check the video in the full post. Granted, it’s an ad (so take it with a grain of salt!), but it shows design details that were not disclosed before. This video shows how the phone was structurally designed to be more compact, and yet very rigid. It’s a 1mn video that’s worth checking out if you like thin smartphones. Also, don’t miss our complete review of the Motorola RAZR.
