THIS PHONE METAL BODY WITH GORILLA GLASS IV MAKES IT PREMIUM BODIED CELL. THE PERFORMANCE OF THIS PHONE IS FLAWLESS. IT IS CAMERA IS BEST IN CLASS. THE BIGGEST ADVANTAGE IS IT DOES NOT GET AS HEATED AS ANY PHONE. BATTERY TAKES AROUND 80 MINUTES TO FULLY CHANGE SO I WOULD SAY THAT FAST AS IT DOES NOT HAVE TURBO CHANGING FACILITY. NO LAGGING. BEST FINGER PRINT SENSOR.
