Stop or reduce motion on iPhone
If you don’t want visual motion on your iPhone screen, you can stop or reduce the movement of some screen elements, such as:
Parallax effect of wallpaper, apps, and alerts
Screen transitions
Siri animations
Typing autocompletion
Animated effects in Messages
Go to Settings
> Accessibility > Motion.
Turn on or off any of the following controls:
Reduce Motion: Reduces the motion of the user interface, including the parallax effect of icons.
Auto-Play Message Effects: Allows the Messages app to automatically play full-screen effects. If you turn this setting off, you can still manually play effects by tapping Replay below the message bubble.
Auto-Play Video Previews: Allows apps such as the App Store to automatically play video previews.
Dim Flashing Lights: Automatically dim the display of video when flashes or strobe effects are detected.
Limit Frame Rate: Limits the maximum frame rate of the display to 60 frames per second (on models with ProMotion display technology).
You can apply these effects to specific apps; see Customize accessibility settings for specific apps on iPhone.
Important: Your iPhone uses an on-device algorithm to detect flashing or strobing lights included in supported video content and automatically dims them on your device in real time. Motion settings should not be relied upon in circumstances where you could be harmed or injured, in high-risk situations, or for the treatment of any medical condition.
