I got a Galaxy Nexus (LTE) on December 15th from Costco. Last week I exchanged the phone due to a repeating issue I was having in relation to the microphone. Since the initial exchange, I have since exchanged it two more times and am on my fourth Nexus overall and it still isn't working. I've also received a new SIM card each time.
The problem is that when I go to communicate with the outside world (text, voice, data) it will work for a few minutes then it will all of a sudden tell me I have no connection and my signal will go from strong (a few bars with the 4G symbol) to completely black with no 4G logo. After 30 seconds or so the radio kind of "resets" itself and then it will work again for a few minutes. It will continue doing this even if I'm not using the phone because my battery went from fully charged to dead and turned off in less than 5 hours.
After speaking to Verizon customer service, they are "working on a solution." What I found, which is interesting, is that if I go into the Mobile Network settings and change the Network Mode from "LTE/CDMA" to "CDMA" (so no 4G connection) my phone works fantastically, no issue at all whatsoever. I even just had the phone go 1 day, 15 hours off of one charge! After that, I switched back on the "LTE/CDMA" to test it out and it immediately started the problem up again with my connection resetting. Turned it back to "CDMA" and it's back to working.
I'm still waiting to hear from the Verizon engineers, but does anyone have any experience with this? Maybe a suggestion of what the heck the problem is???
