I am reviewing this device after using it for 2 week. i must say that it is a killer device at this price segment. specs wise, it has been equipped with high end features. call quality of this device is good, volume is jot that great but acceptable. battery of this device just about average, i was able to get 18-20 hours of life on moderate use. camera is the only disappointing factor according to me, can shoot some decent images but not that great but we cant expect much in this price range. performance, here it steals the show. its performance is super smooth, thanks to that 3 gb of ram. surprisingly, gaming performance of this phone was also very good. the fingerprint sensor works very well and is very accurate. best part is that you can lock any of your app using fingerprint. i would recommend you all to go for this blindly.
