I just upgraded my phone to a galaxy s7 from a note2 - ever since I upgraded (laugh out loud more like a down grade), my phone service sucks. It is always drops calls, can't receive calls and service is spotty. It turns out my daughter is having the same issue. Is anyone else who just bought this dumb phone having same issue? And can someone please tell me how to return it so I can try a different phone. PLEASE PLEASE HELP
