The Zenfone3 Deluxe series is a new achievement of exploring craftsmanship from ASUS. In addition to the powerful specification, we challenge the limitation of physics to push Industrial Design to a new realm. To avoid signal shielding, a hole has to be bored in the metal back cover on smartphones and filled with plastic or glass. However, that is not acceptable for the ASUS design team. ASUS used the agile industrial design cogitation to achieve both a perfect metal appearance and a good antenna signal exit in the ASUS Zenfone3 Deluxe.
