9 years ago Gles.js currently does not support scaling the Canvas element. This requires rendering to an off-screen texture which is then rendered scaled to the screen. In case no scaling is needed, direct rendering provides a performance enhancement which is significant in some cases. If you use upscaling to improve performance however, then canvas scaling is probably the best solution. I think canvas scaling should be an optional feature.

The following code in Phaser does not work. The standard Phaser tutorials look tiny in the bottom left corner of a mobile phone or tablet and need to be scalable to fill the whole screen.
game.scale.scaleMode = Phaser.ScaleManager.SHOW_ALL; game.scale.setScreenSize( true );
