I'm on my 2nd V10 now, which up until this point has been working fine. This morning, however, while in the Google Voice app, I noticed that the 4G LTE icon next to the signal strength indicator disappears and reappears repeatedly. When the icon disappears, GVoice notifies me that I have no connection, which goes away when the status bar indicates I have data. I've tried cycling data on & off, rebooting with no SIM card, and cycling airplane mode. None of this has worked. Anyone have any thoughts?
