I am going to reiterate for anyone who forgot.

If you get an iPhone thrown at your face and it makes contact around your cheek/eye area, it is GOING to hit bone.

This means that the strength of impact is going to be significantly increased.

Consider when you bump into something in a "fatty" area like your upper arm or butt. It doesn't hurt as much as when you plow your toes into a wall, does it? This is because bone pain and injury in close proximity to bone is always significantly more severe.

An iPhone striking someone's face after being thrown ACROSS a room, which means it will be traveling at a fairly high speed, hitting a cheekbone, is GOING to break the skin. It will cause a laceration, and it will cause significant and almost immediate bruising and swelling.

Furthermore, the physical aftermath of such an injury is going to last at least two weeks. You will have bruising at the point of impact for a very long time, and the bruising will extend into your eye area, your nose, and around the side of your face.

It will be somewhat of a surprise if your cheekbone or bones in that area don't sustain some kind of fracture.

In conclusion, if Amber Heard had really been hit in the face with a phone thrown across the room by Johnny Depp "like a baseball pitcher" everyone and their mother would have been able to tell and she would have needed medical attention, not just help from Amanda de Cadenet.
