Do you also have a screen protector? Hair could create some trouble.

If you believe there is something wrong, 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.
How to backup?

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.

Before you try the suggestion Samuel gave, you can check if the same occurs in safe mode:

/t5/FAQ/How-to-boot-your-phone-into-safe-mode/m-p/348008#U348008

If safe mode doesn't help and you are not eager to repair software, you can try to remove screen protector,see if it helps.
