I am using this phone since last 6 months. According to me the performance of phone in this price range is somewhat good. It have a 13 MP back camera with a led flash. The 2.5 D curved display makes it more good in look. One of the best feature that is have Snapdragon chipset.though it is not soo powerful.but it has a snapdragon chipset.
Games such as Asphalt 8, Asphalt Extreme, COC etc runs smoothly in this phone.
If we talk about the bad specifications or you can say that which is not good are the cameras.
The photo quality is not soo good as we expect from a 13 mp camera. If you will use internet regularly.phone won't give you good battery backup.
