Apparently, not all is rosy with some of the owners of the new international version of the Samsung Galaxy Nexus. A small sampling of users are experiencing a volume/muting bug with the phone, and there are enough people experiencing it that it isn't an isolated incident. Several users have posted in forums around the web with the following issue: basically, the phone will sometimes mute itself, and then, "...respond erratically to presses on the volume rocker, if it responds at all."
The one common denominator that users with the issue have been able to determine is that the phone experiences the problem while in a 2G data connection mode, and that it is related to that radio. The video above is from Duddyroar, and demonstrates the problem. Strange...
