Update regarding RF performance. Over the weekend I was in a location with known poor coverage. We have 3 new phones - iPhone XS, XS Max, and LG V40. The iPhones had no trouble picking up a usable LTE signal inside, but the V40 would only connect to an 800MHz CDMA signal, and the data was barely usable. Similar to previous experience there, I had to go outside to pick up the LTE signal. Given that the iPhones were able to use LTE, it was disappointing that the V40 couldn't. Even though it wasn't any worse, it also was not any better. I didn't know if there was a way to see what band of LTE the iPhones were using, so I am not sure what they were using. When I would occasionally roam in the house, it was usually reported as US Cellular, band 12 I believe, by signal check pro, and worked pretty well.
