In the last few months it's been difficult to make calls in my house with my phone. I get texts but the network strength is one or two bars at most and often will say 1x even though I'm in an 4G LTE area. If I can get two bars it's still iffy whether I can make a call and if I can it will get dropped. My husband's Droid works fine so I don't think it's a network problem. I tried turning on HD calls and WiFi enabled calling. Neither has helped.
