Display upgrade

If you had a third-party screen installed in your phone, you may see a message like

Important Display Message

Unable to verify this iPhone has a genuine

Apple display

The message will remain in one place or another, forever.

If the screen was from Apple and you see this message, it may be a sign of a malfunction.

Did you have your screen repaired at apple or at an apple authorized service center? If not, it could be that there is a Non original screen installed, and that is not good for the performance of your iPhone.

If you went to apple or to an authorized service center, I would suggest that you contact them for help with this problem
