mine did it once no coverage at home on 3g only called verizon and they told me to take out the battery and sim card for one min. it then worked fine since about 4 days still good. they told me to leave on 4g tough.
I called Verizon, and pulled my battery, and when I put it in IT DID NOT WORK. I just waited a day or two, and my signal was back to normal. I was on the verge of returning my Nexus.
