I am using micromax canvas nitro 4g. I am facing 1000s of problems in it. It is being hanged 1000 and more times in a day but yet is a Indian. And when we start internet it get hanged got 10 minutes also I never use it very hard till I use it smooth then also it is hanging. A very good thing in this is, it is a 4g mobile and it is supported for both sim slot also this is not have hybrid sim slot. And the best thing is I just buyied it in 6, 110 then this price for the 2GB Ram, 16GB Internal, Snap dragon 415, Gorrila glass 3, 13MP back camera and 5 MP Front Camera in this price is the good phone but hard user hate it as well as smooth users.
