iPhone 7 poor signal
after updating 10.1, my iphone 7 still get 2 or 3 signal strength. I put the sim card to my iphone 5 and it's 5 signal strength. I lived in downtown, dc, so it shouldn't have this signal problem. And I use at&t. Does anyone have the same problem even you updated 10.1. I am not sure it's hardware problem or software problem. I just disappointed about apple.
