I was purchased that mobile before 18 month ago. It has1 gb ram and 16 gb internal memory. Its hardwareis not good and haspoor quality of display. Its hangs quickly in a regular interval. I face many problems while using this. Its battrey backup was very poor. I changed its battery two times in few months. This is my horrible experience with karbonn brand. I recommend to all people they will not buy this handset.
