According to me Karbon k9 smartphone is very bad smartphone because it has no many features like other phones and look of this phone is not good . the Ram of this phone is only 1 gb thetefore we can not install more fabourate apps and the big thing is that it has only 8 gb internal memory therefore we can not store much data. And next some days it going slow and we boured with this . I also used this phone it was going slow therefore I give up this phone.
