Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

I suggest that you to run your phone in safe mode for a while to check if you still experience this. If not this may be caused by any downloaded application.

If it's the same while in safe mode, I suggest that you try to repair the phone software using PC Companion..

Before repairing your device you may want to backup your information first. Check out this topic for more information on how to.

If the issue should still remain I think that this needs to be examined and fixed at a repair center. For more information about how to submit your phone for repair and where, contact your local support team.
