My biggest mistake in life is to buy a Karbonn mobile.please dont go for it no matter whatever high end specs available.they just simply dont work.
They really take customer's money for a toss. Battery sucks, display sucks, build sucks.altogether the brand itself SUCKS
Lots of problem
1.No battery backup
2.Not support 3g
3.Not support App, maximum size of 30 mb
4.Cannot store more App due to internal memory is less n lots more problem plz don't buy this phone.
