True flagship killer. It's been more than a year I purchased this mobile because of its specifications and looks. I purchased a 16gb, its light in weight with premium looks, good screen, easy to hold can be operated with one hand, Good Processor speed, nice camera, custom operating system, crisp audio and video quality . The best quality is that switching apps is fast, playing games is fun as it Handel's it nicely and does not lag . If u are looking for any change go for one plus one, u will get a premium mobile with good configuration at decent price
