We’ve heard rumors that one of the reasons it’s taking so long to get the Galaxy Nexus out in most markets is that some last-minute bugs may have been uncovered and Samsung didn’t want to fully let the reigns off the phone until they could be addressed. Now that early-adopters have their hands on the model, and have had a few days to dive into it, we’re learning about what could be one of these rumored bugs, and it looks like quite the annoying one.

Galaxy Nexus owners have reported an odd behavior where their phones will wildly adjust their own volume levels, spontaneously muting as they fluctuate about. Many turned to online forums to discuss their accounts of the bug, and a few common trends began to emerge. For instance, this behavior seems directly tied to the phone’s cellular radio, and specifically 2G operation on 900MHz. Supposedly, in areas where cellular signal strength is the weakest, the effects of this bug are most pronounced.

Despite attempts to reach out to the company through the likes of Facebook, Samsung has yet to publicly comment on this issue. With something like 60% of self-reporting Galaxy Nexus owners noting they’ve run into the bug, there’s going to be a lot of pressure to get this taken care of ASAP.
