Juli Clover, MacRumors:

Apple’s iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max will offer up a new warning if a repair technician ever uses a non-genuine Apple display when repairing a broken device.

“Unable to verify this iPhone has a genuine Apple display” will show up in the General > About section of the Settings app if a repair shop uses an unverified display component.

Good to be aware of this if you:

• do your own repair,
• get your screen replaced by a 3rd party shop or service,
• buy a used iPhone

Per that last, if you do buy a used iPhone, that’s the first thing I’d check.
