I also saw this issue today. Looked down and had no bars no 3g. No error messages other than no data connection in my email. Turned my phone into Aiplane mode and back again and seemed to resolve it.
When i go into the battery graph, on the bottom where it says mobile network signal, I have red lines throughout the day indicating that i am losing connection. It is sitting on my desk in downtown toronto, I am not moving around so I am not sure why that is happening. Others with android phones are not seeing this issue.
Anyone else see this issue on their phones? could there be an issue with the nexus and rogers?
I have the same thing happen to me!
Understandably, I lose reception when I go to underground parking (four floors underground) but when I get out, my Galaxy Nexus seems to lose its ability to search/find and connect to the network.
I'll go to Settings -> More -> Wireless & Networks -> Mobile Networks -> Network Operators
And a message comes up saying that there's an error in trying to find/connect to a network.
The only method I've found to correct this is by turning my phone off then back on. This never happened with my old phone (N95 and Nexus One) so I'm pretty sure it's a Galaxy Nexus thing. It doesn't make sense though that once it loses its connection, it can't or doesn't try to re-establish a connection.
I have a two day old Galaxy Nexus on Rogers, and I seem to be having pretty constant data drops. There are occasionally whole signal drops, but they're rare... mostly I just loose the "blue" bars and all my data connectivity is gone.
Additionally, I notice the network flip flopping between H and 3G, sometimes five or six times a minute.
This is all happening in areas where I know (using my previous iPhone 4) that I have a strong 3G signal. All this struggling by my phone to maintain a data connection also can't be good for the battery - so I suspect that some of the battery drain issues I'm seeing are due to that.
