Social app refuses to launch
Have you checked if there is an update for the social app on your phone or available software update for your device? If not then visit the link http://www.nokia.com/global/support/software-update/belle-asha-symbian-software-update/ and check the instructions for updating the application or software of the phone. Before doing so, take a back up first of the files from your phone to your PC using Nokia Suite to avoid data loss.
If there is no update, you may re-install the software of the device by the following instructions below:
Connect your phone to your PC using the USB cable and launch Nokia Suite.
Once your phone is already recognised by Nokia Suite, click on Tools tab.
Select Software Update then look for the "reinstall" button.
