Here is how you can blur your iPhone Lock Screen and reduce the motion to give your iDevice an awesome blur effect!
Start by taking a screenshot of the first page of your Home Screen.
Next we need to blur the screenshot I like using Pixelmator on iPhone but there alternatives like BeFunky.
Import your screenshot and add the blur effect. Note: Don’t make the blur too strong otherwise it will lose the effect.
Save the blurred screenshot to your photos.
Now navigate to Settings App > Wallpaper and customize the Lock Screen wallpaper. Set it to the blurred screenshot you just created.
Next customize the Home Screen wallpaper and choose the original wallpaper you used.
We now need to reduce the motion for the full effect.
Navigate to Settings App > Accessibility > Per-App Settings > Add App > Home Screen > Reduce Motion > On.
Done!
