I updated the device and got "Previous version identical to the update. Firmware not modified. "
Im using google voice, and call quality is terrible. I am disconnected, not able to hear, or their not able to hear Me at some point during about 40% of the calls. Wife was saying that when I called her, my voice was delayed about 4 seconds and very crackly.
I am willing to pay for a service that is more reliable then google Voice, If google voice is the issue.
