shinendrakumar, Sep 6, 2015 : Hey Everyone, I am using Oneplus 2 and I'm facing very major problem in my OnePlus 2. When I call someone my signal automatically disappears and disconnects the call. I'm using Airtel SIM in India. I also contacted Airtel about this they denied to accept any type of problem in their network and it happens with other companies SIM also in my OnePlus 2. I don't know whether it's a hardware problem or software issue.
