    Factory Reset iPhone or Call Apple

    If none of the above fixes make the blurry top-left corner of your iPhone screen disappear, you’re likely dealing with a severe software or hardware issue. Your best shot at fixing the problem is to back up your data and restore iOS to factory settings. If that also fails, contact Apple Support or visit your nearest Apple Store.
