How can I turn the warning sign/message off: Display Unknown Part?

Hello GaryOusby,

We'd like to help!

The only way to get rid of it would be to have the display replaced by Apple or an Apple Authorized Service Provider with a genuine Apple display.

The message won't affect your ability to use the phone while this message keeps popping up.

Let us know if you have any questions.

Thank you for using Apple Support Communities.

Take care!
