It will involve quite a lot of time and effort, but if you reset your phone, reinstall the latest available software and then set up your phone manually all should work well.
1) Back up your basic information Contacts, Calendar, Messages and Notes using the latest version of Nokia Suite which you can get here.

2) After the backup, disconnect phone from PC and dial *#7370# followed by 12345 if required (this is the default pass code) The phone will reset and restart and be as it came from the factory, all info will be gone except the phone operating system, do not set up anything except time and date after phone reboots. Connect to Nokia Suite again, check for Software updates and if none available reinstall latest available version, plus any other options you want, Nokia Maps, Microsoft apps etc Once the software is up to date , set up your phone manually. Restore contacts etc from backup, but NOT settings , apps etc a full restore will reinstall whatever is causing your issue..
Once you have set up the phone, add any media or applications you want or need and you are good to go.
Good Luck
