Hey friends I was purchasing galaxy grand quattro in june 2013 that was my first smart phone after that every six month I change my smart phone.but I never purchase samsung again because samsung phone became lagi after six to eight month.
Only the brand name because of it I purchase samsung brand but the experience with samsung is so baad that I never recommend for samsung brand.
Friends you can buy moto, lenovo, coolpad, xiaomi, meziu brands that give you very reasonable price phone.
