Wrong specs given for a good phone

At sub 5k price range this is a complete package.Very strong that I bought it for my mom 3 months ago and despite my niece banging it on floor nothing happened.For high-end users touch response and camera will not be satisfactory but overall this is a good package phone.

I just received Karbonn K-9 phone through Home shop 18. The instruction booklet letters are so small that I could not read.On rebooting phone say to insert SIM read instruction in book let but there are no instructions on the subject. After I insert the SIM and using it I will further know benefits and shortfalls
