on my previous Verizon phones, there was a selection under Settings that allowed you to pick which "radio" you wanted to use. It appears that my S4 has Global mode selected. In the area where I live, 4G is weak and 3G is even weaker which drains my battery. I was hoping to select LTE instead of Global which is what I used on my old phones. Was this removed by Verizon or have I just not found it yet? It appears that other vendors have this selection under Settings - More
