I've had my new iPhone 16 with Apple's silicone case on for a couple of days now, and today I just noticed that the case seems to be bulging out from the iPhone's frame under the camera button. It's not by much, but there's still a small gap right under it. Is this caused by the "fake" button on the case protruding inwards or a defect? Potentially stupid question, but I can't take off the case right now.
