My Galaxy Nexus is brand new and on two occasions I tried to make a phone call and the phone said "No Service." Data has been intermittant as well. It will work fine for a while then have "no Service." The Verizon Corp. store said they had 4G problems yesterday. I had problems on both Wednesday and Thursday. I live in the Winston-Salem, NC area which should have 4G service. When I cut the phone off and back on, I seem to have service afterwards. I asked if it should switch from 4G to 3G when service changed and he said it should switch automatically. Any one else having these problems? Thanks in advance, WolfpackRon.
