I keep finding my Verizon Note 2 has dropped from 4G to 3G. Nothing I do changes it back (tried to switch data modes, toggle Wi-Fi, etc) except a reboot. When I reboot, 4G is back no problems, but it's a pain, and I can't figure out why it keeps doing this. I would like to think it's a Verizon network issue, but 4G is right back when I reboot, so it's not like a network outage. Has anybody else had this? Is this a flaw with my radios? Any other suggestions? I'm stock but rooted.
