Redmi 1s.Has 1.6 ghz quad core processor which is totally waste it cannot runs games for long time not even for 2-3 minutes.For example Asphalt 8 starts it runs 15-20 Seconds the it closes Automatically.Ram is 1gb but not good because it cannot run even asphalt 8 the whats the use of 1gb ram.camera is quite good being 5mp only.The worse thing that the phone heats up very soon.But its ok type phone in range of 6000/- Rs.But I would say that we should go with any other phone instead of Redmi1s.Thanku!
