I was using this karbonn phone 2 yours before.i purchase it in 4000 but now it is in 2500.look of this phone is very good.i think this phone is good for girls or who do lite work because the processing of this phone is too slow storage is very little.you can do only lite work properly.if you install many applications then it becomes hanging. Battery backup of this phone is not good.But I think in this low price this is a good phone.you can use for calling, watching movies and listening songs.no upgrade feature in this phone.so it is old and takes old features.
