The Android 4.0 Ice Cream Sandwich phone, which went on sale last week, is suffering from a particularly annoying bug.

The glitch sees the handset drop the audio volume of its own accord. The phone goes suddenly silent, without warning, many an owner spent the weekend complaining on the intertubes.

Others have grumbled about the volume key becoming unresponsive, and even the power key sometimes ignores users’ presses.

Not every handset appears to be affected, but the consensus is that the bug only makes its presence felt when the Galaxy Nexus is operating in the 900MHz band for 2G communications. That’s a very commonly used band in Europe.
