A colleague brought me their phone (a Nokia C6-01) and stated they had a problem with it and perhaps I could assist. After an update they'd found they'd lost one of the profiles one labelled Outdoor that increased the ring volume automatically.
I checked the menu system quickly and found no such profile; I checked online and found no-one else complaining - so I headed to Nokia's own site and started digging.
If you try searching with the right parameters something interesting occurs. My first discovery was the South African web page that didn't list an Outdoor profile; however Google had it found with that search term? Pulling up their cached version gave me the reason why. The top version is cached, the bottom current:
So Nokia have removed a profile as part of the system update and then removed every reference to it in the new guides without telling anyone. I wonder how many people are scratching their heads and insisting that it used to be there?
