Samsung just got back with us regarding a fairly serious bug some people are seeing after the recent DL09 over-the-air update for the Verizon Fascinate. Namely, some of you can place an emergency call if you're using the pattern lock feature. The sky's not falling, but it is a potentially serious bug. Here's Samsung's response:
It has come to the attention of Samsung Mobile during the recent DL09 OTA (Over-the-Air) update for the Samsung Fascinate that some users utilizing the Pattern Lock are finding that the Emergency Call shortcut is not automatically launching the dialer. However, unlocking the device will allow the user to make calls as they normally would, including emergency calls. We apologize for the inconvenience and are continuing to evaluate the issue, including if the issue is linked to the update.
Kudos to Samsung for looking into it. For now, we continue to recommend that you not use the pattern lock feature if you've upgraded to DL09.
