Thanks for your post and welcome to the Nokia forum.
In order to fix this isue, I would suggest you to perform a hard reset. First of all, back up your data using Nokia Suite (Tools > Back up). Once your data is fully backed up, type *#7370# on the keypad. Default lock code is 12345.
Alternatively, you may also check for updates on Nokia Suite (by going to Tools > Updates).
The hard reset will dellete all your personal information, that's why a back up is very important.
If the problem persists, I would invite you to visit your local Nokia care point to get the phone checked, If it needs a repair, it could be done there.
Let us know how you get on and feel free to post any other questions you may have.
