Design is average not that bad , not that good . It has got a full metal body chassis . Beauty of the phone lies inside the hood. It is powered snapdragon 430 and has 4100mAh battry , speaking of which the battry life on this device is amazing it can easily last u for a full working day. It can also play heavy games like asphalt 8, nova 3 fine on medium settings. It runs on mi's own ui which works fine for most parts. Camera is not so good in day light it can shoot some decent shots, but when we move to indoor lighting and artificial lighting, it struggles a lot. Display is average on this device though.
Over all it is a good value for money. If you are on tight budget and want a decent phone certainly have a look at this.
