Well! Sony, this name is good enough to show the status and preference of a person. Xperia C4 comes with dual sim technology. I bought this phone a year ago for Rs. 24000/-. This phone has got a good quality picture camera offering 13 mp rear and 5 mp front with LED flash in front & rear both. It has got 11GB internal storage memory which is expandable to 128 GB. Battery life without using internet is good. Battery can not be separated from the phone. It does not accept micro sim card but a nano sim card is compatible. It has also got a good quality sound system in it. Sensors works really well. This mobile is featured with many apps in built. Only disadvantage is that phone is heavy and large to carry. But still, I would prefer you only this model if going for SONY.
