Samsung z4 comes 2050 milli amphere battery backup which is pretty good I guess user with not so long use of cell phone can buy this product. It has 5mega pixels camera and with a nice flash so the quality of pictures gaken in this phone is pretty good.
Samsung z4 has 1gb of ram which is random access memory and it is not so speed the price with which they are delevering the phone is not so sufficient regarding the specification so its good to go phone can take the phone.
The apperence of the phone is nice and simple.
