Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.
Do you mean that your phone is bent? If that is the case, I suggest that you visit nearest service center to have your phone exained by a technician. Your local support team should be able to give you further information about nearest service center and/or how to proceed with this in the best possible way:
