Got an Xperia Z3, gave it to a lad from football to fix the screen and it's come back with broken camera and earpiece. He reckons this is a common fault, that if you don't have original earpiece then camera won't work. Phone worked just fine (bar broken screen) before he had it. Does any of it ring true? Not that I even know where original earpiece would have gone anyway, or why he replaced it.
