The promised volume bug fix for the Samsung Galaxy Nexus is now rolling out over-the-air, with multiple Nexus owners reporting that updated software has arrived on their handsets. The OTA package weighs a little under 1MB, and updates the Nexus from build ITL41D to ITL41F, while the Android version remains at 4.0.1. So far it seems that the update contains only the volume bug fix, and that there are no other goodies hiding inside.
If you've noticed the bug on your device, you'll want to head straight to Settings > About phone > System updates to grab the new software. At the time of writing, not all Nexuses have received the patch, so if you don't get it straight away then be sure to check back in the hours and days ahead. Unlike previous Nexus devices, there's no easy way to directly apply apply the OTA package without unlocking the bootloader and rooting the phone or other such hackery. If you're comfortable messing around with Android's software internals, though, we've figured out a way for you to apply the OTA update manually, without waiting. Check it out.
