Who observed the home screen of his iPhone 6S noted that the contents as icons, wallpaper etc. move, if you tilt the phone. These movements of your home screen are related to the so-called parallax effect. This motion effect makes it possible that you always can see the contents of your smartphone in 90th ° angle. More information about the parallax effect can be found here.

Step 2: Tap on General --> Accessibility --> Reduce Motion
Step 3: Push now the slider "reduce motion" from "Off" to "On" to disable the parallax effect in symbols and signs
