I recently noticed when I was cleaning the screen of my phone to replace the protector that when I press a little harder on that area of the screen (see picture) I hear a very soft popping sound. It sounds a little strange. Does anyone have something similar? I had spoken to a technician because there is no apple store in my country and he told me that it would be normal because there is a hollow space in this part of the phone (that is, few components)
