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

This sounds more related to a hardware issue than something faulty with the software. I suggest that you visit nearest service center to have your phone examined by a technician. You can contact your local support team for further information about nearest service center and/or how to proceed with this in the best possible way:
