I do not live in a 4G area, and have dutifully turned of LTE. All along I was on CDMA mode and received 3G signal. In the last few days I only get 3G if I turn on LTE, otherwise no signal. I called and reported to VZW, but no solution yet. I have done the battery-remove reboot. I have been exhausting the battery on LTE while not getting LTE signal.
