Hall writes "In the last few months some users of Verizon Wireless HTC Eris phone models have encountered what's being called the 'silent call bug' with their phones. What has happened since the update to Android 2.1 is that some phones get dead silence (can't hear the person they call nor can the other end hear you). The only solution is to reboot the phone, though the problem will re-appear after some time. VZW tech support for a while was simply swapping out Eris phones in hopes that the replacement didn't have the same issue. Too many were, though, and now some users have been told they're not swapping anymore. A couple of days ago, a user witnessed a car accident and was unable to call 911. Well, at least not until after rebooting the phone."
