What does that do? I tried it and it only disabled parallax, but in settings it says it "reduces the motion of the user in face including the effect of the icons and alerts. I don't see any difference on the "effect", but it seemed of to speed up my iPhone 5, like opening up multitasking no stutter when first opening it. Can someone see if it was just me? Or does it cause no effect on sowing down my phone. Also can you notice an parallax effect on the second blue dynamic wallpaper?
