I have used I kall n4 tab white color. And I bought it from snapdeal Rs. 4200/- its battery is very poor. And charging speed is 4 hours. The networks system is not good. In use of 30 mint continue it’s get hang, if you try multiple apps running it’s probably process become very slow. And it’s function's and touch are not working properly. it’s looking was good but it was not good for me. The customer service is average but I have no service center near me.
The networks system is so poor. So I don’t understand with this and don’t recommend anyone else.
