I bought Karbonn a21 3years ago.Karbonn a21 is easy to carry because of its size.Karbonn a21 camera is also not too good in this price point.I bought Karbonn a21 in 10k.Karbonn a21 is expensive in price also.I install many apps on my karbonn a21 and its motherboard crached unfortunately.Karbonn service center also very bad and too late.Very Bad experience with Karbonn a21.
