I buy this mobile from my friend. The look of this mobile is good. But the battery of this mobile is too short. It does not work for a whole day. The phone shut down with in 4- 5 hours. The ram of this mobile is 1.5 gb, until at this time everyone wants to a 2gb, 3gb, 4gb ram in a mobile. I want to change this mobile. Because this is not working properly. And the range of this mobile is very costly. Thanks
