Belive me this is a great mobile. I am using this mobile for 1yr Amy my experience with this device is great. There is no lag in this device. I dont need to say the specifications. 3gb rag is running this device buttery smooth. I have played Novak, asphalt 8, mordan combat 5 and I dont see any lag.
Display quality is also great with 401 ppi. Full hd screen. Nice experience with movie, game, videos. And images.
Camera quality is average. Day light pictures are realy good but night or low light pictures is not that much.
If you want a monster /beast under 20k with good quality hardware. Then go for it.
