Did you Get a New Screen?:

If you are getting the notification, then the issue is that is an ungenuine display. So, did you have this screen replaced? If so, then ask the person who replaced it to replace it once more, but this time with a genuine screen. Elsewise, you'll continue getting the notification. They should have known better.  Learn More here: About Genuine iPhone Displays - Apple Support
