The main draw backs in samsung galaxy s duos 2 s7582 are
1)battery back up is very poor.
2)in this mobile phone ram is also less.
3)the hard were which is provided by the samsung is very less quality.
4)when you observe the back panel of this mobile phone it is very lite weight and it is easily get damaged.
5)this phone is always hangs then compared to other mobile phones.
so I did not prefer to buy this mobile phone.
