On mobile your finger is often obscuring the button you press and an animation is necessary feedback. This is especially important for things that are not booleans, for example a button to increase a value and you end up in "wait, did I change it to 5 now or was it 5 before with my press not registering?" (actual example from yesterday in a famous D&D helper app).

Surely this only happens because someone wasn't looking at the screen while they were making the input. They could just as easily miss whatever animation is attached to the number changing. The real solution here is to provide some kind of haptic feedback (phone vibration) or to play a sound.

  Big disagree on that. Sound and haptic feedback are clearly inferior solutions to the obvious one: an animation.

    Can you back up this opinion with any kind of coherent argument? Because the problem is "people can't see the screen" so I feel like displaying something on the screen might not solve it. By contrast, you would definitely know if the phone buzzed when you clicked a button. Anyone who's ever used one of the iPhones with fake home buttons on them can attest to this fact.

If the animation is so slow that it is still visible after your finger isn't obscuring the button anymore, I'd argue it has to be really slow and is not snappy anymore. It also doesn't behave like anything physical, because physical buttons/sliders only move while you're touching them. The gold standard used to be to make buttons large enough so they are never fully obscured (for toggles, the label can be included to be part of the button) and to highlight them when pressed and remove the highlight when released. (Like keys on a virtual keyboard mostly still behave.) That way, you have a clear indication of when you press something, and it coincides with what your finger is doing, and doesn’t lag behind.
