I have these animations in my phaser.js game:

this.anims.create({
        key: 'catchingUp',
        frames: this.anims.generateFrameNumbers('android', { start: 0, end: 4}),
        frameRate: this.frameSpeed * 6,
        repeat: 0
    });

    this.anims.create({
        key: 'catchingDown',
        frames: this.anims.generateFrameNumbers('android', { start: 5, end: 9}),
        frameRate: this.frameSpeed * 6,
        repeat: 0
    });

    this.anims.create({
        key: 'topTop',
        frames: this.anims.generateFrameNames('androidTopTop', { start: 0, end: 9}),
        frameRate: this.frameSpeed * 6,
        repeat: 0
    });

    this.anims.create({
        key: 'downUp',
        frames: this.anims.generateFrameNumbers('androidUpDown', { start: 0, end: 4}),
        frameRate: this.frameSpeed * 6,
        repeat: 0
    });

Only the animation with key downUp works fine across all devices, it's the only one where the sprite just moves it's arm and doesn't go from one side to the other. Animations with keys catchingUp and catchingDown cause a black rectangle appear on the screen instead of my sprite; on phones and tablets, despite working fine on laptop. I thought the problem was animations themselves, because character skips several frames, so I've made another animation topTop, same problem. Then i thought to put all the animations in one spritesheet , but that only caused all of them to be a black triangle, including 'downUp' animation which on it's own worked fine.

I've seen someone else asking similar question here and they were advised to use this.anims.generateFrameNames instead of this.anims.generateFrameNumbers, so i did that. Same, worked fine on desktop, black triangle everywhere else.

Before, when I used non animated images, instead of animations, it worked fine across all devices.

The game in it's current state can be found at https://chylinski82.github.io/androidCoop/ and all the code on https://github.com/chylinski82/androidCoop, the animations are in Level.js and they're called from basketUpRight.js, basketUpLeft.js, basketDownRight.js, basketDownLeft.js.
