“Non Genuine Display” Message in Settings

The message will remain until the display is replaced by a qualified service technician using the correct tools and procedures. It is unlikely that any service center will remove the message for you without also replacing the display.

I do not own the tools, nor do I desire to. However, if the device was brought into a Certified Apple Repair location, surely they could remove this message, right? It comes back after you reset the device.

IF they agree to service that phone, which is doubtful, the only way they will agree to do that is to replace the display you installed with a service part from their stock.

IOW, you're going to have to pay to have the display replaced by Apple or an authorized service provider. And that's the best case scenario.

Worst case, they turn you away and refuse to service it, in which case you can either live with the issue or buy a new phone.

You can’t.

Not without tooling you don’t have, and can’t get for an iPhone 11.

Ignore the message.

It’ll get less overt over the next weeks.
