Android has really failed at this. Android apps are full of animations that serve no purpose or are even misleading, and slow down the experience. It's cargo cult copying from iOS. And the animations are janky, too.

Luckily Android has a developer option to double the speed of animations system-wide. It's the first thing I turn on every time I get a new phone. I find that double speed is about right. Designers tend to make every animation at least half as fast as it should be, to make sure you notice their effort.

One that gets me routinely is Android's two-stage quick control/notification drawer, which is further complicated by gesture-expandable notifications. It feels like a poorly thought out bodge to fit everything into a single screen. It’s annoying to me even as a software developer and must be terribly confusing to someone not well versed in the arcane incantations of mobile operating systems.

There's an accessibility setting to disable all animations and the result is even better, it feels like living in a future where everything is instantaneous.
