I don't see how that could happen but do contact your local Xperia Care

Have you been overheating the phone a few times recently? And how old is your SP?

Yeah its best to contact and bring it to your local Sony Center

looking at that picture, are you sure you didn't dropped the phone or maybe sat on it, etc

It is been not hot or bent it all works without any problems

It's a join between aluminium and plastic part. I am sure it's a factory defect.
