Yes, I noticed that as well--a bit misleading. I'm not sure why everyone is saying its a "solid block of aluminum" when in fact its an aluminum back with plastic sandwiched in the middle with the metal parts on the other side glued on. All smartphone makers use glue by the way, including Apple, but its how they use it that matters. Sometimes you need glue, and other times its better to use screws or brackets.
Ok the phone is a single piece of aluminum..there is silicone or plastic molding injected into areas of the phone back for the antennae etc. The speaker broke off in the video at the place it was weak. There is no screws or partial pieces put together or glued
