This smartphone has a double layer design that places its most important features in optimal positions. The front contains robust hardware and software, with the LCD screen, the main interface, protected from damage by hard 7000 series aluminum. It also has an iris authentication sensor that enables smart and secure protection of personal information. In contrast, the rear has a fiberglass mixed resin case with soft corners that does not easily slip in the hand, in order to fit the gestures and ways of holding the device depending on the app being used. The case contributes greatly to both the torsion strength and network signal sensitivity.
