I have been using this phone for over a month.
Phone signal perception stability : worst
Data connectivity: worst
GPS: worst
Speakers: worst
Headphone: worst
Video recording: good
Photo: good
Fundamentally it sucks at all the core features. This phone is not worth more than Rs 4000At the same time, I checked with Micromax canvas hd too. Both of these are craps.
I suggest any one looking for good phones, go for Sony or Samsung or htc
