Nokia C6-00 - Why does SW Update always show “software is up-to-date” even though the other users seem to be installing many applications via SW Update?

Some applications are not published to all operator variants and all country variants for legal reasons. So, if your device belongs to any of these variants, you would not be seeing these applications in SW Update list.

If the applications are already installed on the device via other means like “download”, then SW Update will not display the same version again but will only display a higher version of the application.
