Turn Off System Animations auf Samsung
Some Samsung users notice discomfort, eye strain, or mild dizziness when menus slide, fade, or bounce during normal navigation. Samsung ties this motion control to an accessibility function rather than the general display settings, so it is easy to overlook.
The option lives inside the visibility tools Samsung built for people who need reduced visual stimulation. Turning it on strips away the transition effects used when opening apps, switching menus, or minimizing windows.
To reach it, open Settings ➤ Accessibility ➤ Visibility enhancements, then enable or disable Remove animations.
Once enabled, screen changes happen instantly instead of transitioning. Some users also find the phone feels faster, since there is no waiting for a transition to finish before the next tap registers.
This setting affects only the motion transitions built into the system interface. It does not change video playback, animations inside third-party apps, or effects tied to live wallpapers.
If your real concern is slow app switching rather than motion sensitivity, check background app limits instead. That is a separate setting and won't be solved by removing animations.
