You can stand in the middle of a door and you can see through the door. It happens on every device that has bedrock edition as far as I know. It technically gives you x-ray. I don't have any photos but I will explain. You stand in the middle of the door, shut the door and then your in between the door and you can see through the door. A simple solution in shoving the player right outside of the door if they try to do it.
