It is a bad product from karbonn.
firstly ill start from tech having 2 gb Ram is not enough for multiple tasking
and 1.3 ghz processor is not enough to run a phone without freeze.
it has 4000mah battery its not fair battery actually its getting heated and heated it causes irritating.
it has 13mp rear and 8 on front but its not better choice when it comes to camara its not that much good picture clarity.
And the touchscreen is not that much fair when compair to some of other phones.
