Coming from a MAXX

I don't get any 4G in the building I work in. As soon as I step out the door I do.
4G works fine though.
 
Well as luck would (or wouldn't) have it; the battery, according to VZW, is defective because it is overheating(getting hot to the touch on the back where it says "Galaxy S III" sooo they are supposed to be shipping one out.. couldn't get into a VZW store for a quick exchange because of work hours.. ugh
