I work in a building with a metal roof, so reception is poor at best. I recently "upgraded" to Lollipop and the situation got much, much worse. Instead of one bar, I have none and then, "no service." The phone does not recover when I move to an area where I have a cell signal. I have to reset the phone to get it talking to the cell net again. This is not acceptable; any thoughts on how to convert my overpriced paperweight back into a reliable phone?
