Best mobile in the 4inch screen size . I have purchase this mobile because my buddget is low 4G speed is very good . but androide os is better than tizen os . Battery backup is to low and its camera is better in this price . Front camera is vga so it is bad for buyer. Processor is good . and its Ram is good 1 Gb. Samsung brand is trusted brand because its service is fat and in my life I have purchase only samsung brand.
