How to remove the message for unable to verify this I phone display
iPhone 11 Pro Max, iOS 14
Did you just get your Display (Screen) replaced by a third party repair shop? If YES then at the iPhone is telling you that your display is not a genuine Apple Display.
You will see a notification on your Lock screen for the first 4 days that you use your device and in the Settings app for 15 days. After that period, you can find the notification by going to Settings > General > About.
