Well it worked for me you must do the process stated above from the locked idle screen tap power button once quick tap to shut off display then repeat that to turn screen on then follow the from prompts stated below)in order for this to go away you may have to hold home button and the power button for about five sec and that refreshes all open windows apps then do this from the locked screen hold both the power button and volume down button at the same time until your screen displays the Apple logo and then upon reboot the Apple butter bug as I call it will disappear has not returned as of yet so all will and should be fine
