After replacing the display of your iPhone at a repair shop outside an Apple Authorised Service Provider, you might get a sudden flash message on your screen saying —
“Unable to verify this iPhone has a genuine Apple display.”
The good news is that the pop-up appears only once, immediately after the replacement, and then disappears, so it’s not a major issue.
However, the real concern is that your service history will permanently show the part as an “Unknown Part.”
To check, go to Settings > General > About Section.
Why Does This “Unknown Part” Message Appear?
iPhone components — like its screen, battery, or camera — have a tiny IC (integrated chip) attached to them. This chip carries a unique serial number that’s digitally paired with your iPhone’s logic board during manufacturing.
When you replace any of these parts outside an Apple Service Centre — even with a genuine one — your iPhone’s system checks that serial number and says:
“No… I am not recognising this part.”
That’s when it flashes the warning — “Important Display Message” or “Unknown Part.”
Does This Affect the Performance of the Replaced Parts?
No, not at all.
Your replaced part will still work perfectly — the screen will respond smoothly, the camera will function normally, and the battery will charge as expected.
It’s not a fault — it’s just Apple being extra careful.
Note:
If the replaced part is OEM, your iPhone’s performance won’t be affected.
However, if a low-quality or copy part is used, it may lead to issues like reduced touch sensitivity, inaccurate colour display, faster battery drain.
How can we remove these warnings?
At Mheal, our expert technician carefully removes the original IC (the one carrying your iPhone’s registered serial number) from the damaged display, battery, or camera and fits it onto the new replacement part.
This process keeps the original serial number intact and synced with your iPhone’s motherboard, ensuring full compatibility just like before.
