I bought this phone 1 year ago for Rs. 5400 and I am still using it.
As far as its specifications are concerned, It has got 1gb ram, 8gb internal memory, 13 mega pixel rear camera with dual flash and 2 mega pixel front camera without flash. It has got gorilla glass 3 protection for its 5 inch screen, It supports 2g and 3g there is no 4g support. Battery is 2600 mah.
Now its performance: It lags a lot inspite of 1gb ram, somtimes it goes blank if 2 or 3 applications are running simultaneously, camera quality is poor [both rear and front]. Only good thing when I bought this phone 1 year ago was its price. This phone looks too good. But now much better phones are available at same price range.
So I won't suggest anyone to have a go for it.
