Social has multiple components. Select Menu > Settings > Installations > Already Installed (On Symbian Anna, select Settings > Application Manager > Installed apps) > to check if there are still other Social components installed on your phone, including:
- Social Facebook Summary Widget
- Social Facebook Widget
- Social Home Screen Widget
- Social Installer
- Social Installer Helper
- Social Twitter Widget
Note: Amount of the components may vary depending on the Social client version.
Uninstall all the Social components, restart the phone, and then re-install the Social from Nokia Store (search Social Networking Client) or via SW Update. The preferred method of uninstalling is by long-pressing the name of each component name, then choosing Remove (or Uninstall/Delete depending on your device OS version).
