I have 2 lines on my account. We both use the Note 3. For several months I have had poor service within my house. It's gotten worse. I was able to sit outside and make calls, but that's not even an option. Is this due to the update? Is there a new update being released? Customer service is of no assistance. Our zip is 52732, they say there are no known issues in our area so, what's the deal?
