Game world scale problem

[Echoes]

Hi.
My game size is  :  var game = new Phaser.Game(640, 780, Phaser.CANVAS, 'game');
I have resized it to :  this.world.resize(640, 10000);

player position : this.player = this.add.sprite(320, 9952, 'player'); this.camera.follow(this.player);

When I am using scaling, such as :

this.game.world.scale.set(2,2);

or

gofull: function () {

            if (this.game.scale.isFullScreen){
                this.game.scale.stopFullScreen();
            }
            else {
                this.game.scale.startFullScreen(false, false);
            }   
        },

it set my player and camera position 0, 0 ( at the top of the game ),  

when using gofull() function it only changes position when fire stopFullScreen(),  with startFullScreen() there is no problem
I'm probably wrong to use resized world and scale.
