I have Samsung galaxy s7, whenever I am using internet in my mobile using cellular network like airtel and in between I got a call when I answer the call after that my internet is not working I have to restart my device only then 4g network is coming, I am facing this problem very much because restarting again and again is not good.
Therefore please suggest me what to do so ad to overcome this problem.
