I feel hexa is very good and perfect. But as we compare Karbonn Octane plus and hexa, hexa is good shape and screen length. Dual core means to chips, quad core means four chips, but Hexa core means eight chips. So that it means that the Hexa core is the best among these.
This phone is good for people who looking for everything including 2 GB RAM 13 megapixel camera under 15k. This phone is far far better in quality, and price is really good in budget. Everything is good like camera quality is a nice, sound quality is good
Pros:
As all have said no lag.
KitKat is awesome.
13 megapixel rear camera and 5 megapixel front camera with gesture clicking.
Lightweight.
Moderately easy to operate with one hand.
So please buy the phone.
