Samsung galaxy s duos 7562 is a worst phone that I used in my life. No doubt samsung is a good company so I believe in samsung but when I purchased this phone I totally disappointed . This phone was hanged very quickly sometime when I am calling it will be hang.
Battery back is also very bad . It works too slow, looks too old, camera quality is poor, ram is also not good. No multitasking work can do in this phone.
Overall this phone is not good . Never purchase this phone
