I was test on Android, iPhone, but it works every time, the this was first time…!
does any one know how to resolve this problem?

config code:

    var config = {
        type: Phaser.AUTO,
        scene: [Preloader, TrebirdClefMiniGame, GameUI, MainMenuUI],
        physics: {
            default: 'arcade',
            arcade: {
                gravity: { y: 0 },
                debug: false
            }
        },
        pixelArt: true,
        scale: {
            parent: 'GameContainer',
            mode: Phaser.Scale.FIT,
            autoCenter: Phaser.Scale.CENTER_BOTH,
            width: 90,
            height: 150
        },
    };
