Low music cannot be heard at all, apparently.
Following the launch of the Windows Phone 7.8 update, Nokia's Lumia 800 smartphone has suffered low volume issues.
Music was previously loud at the volume level of 15 before the update's roll out. However, some of the device's owners have now said that it has to be turned up to 30 in order to reach the same level of volume achieved prior to the upgrade.
Meanwhile, music being played at a low volume seemingly can't be heard at all. The update itself is from where the issue stems, as reflashing Windows Phone 7.5 back on affected handsets removes the aforementioned volume problem.
The Lumia 800 isn't the only Nokia smartphone with audio issues. The Lumia 920 and 820 see audio being capped automatically upon loud music being played, with the problem being eliminated only once a reboot is performed.
