What's with the screws on the 920?

So much for standardizing the port location - they forgot about the orientation!
Maybe to hold the screen in place maybe. Because that's how you disassemble the device, by taking the screen out.
I think for the Lumia 900 you had to take out the SIM tray, then there was some sort of pin or something behind there that held the screen in place.
