The best way to know if a display is an iPhone screen is by checking Apple’s Parts and Service History and not by the looks of the screen. If you have a supported iPhone running iOS 15.2 or later, go to Settings > General > About > Parts and Service History. If you used genuine Apple parts and techniques to install a replaced display, you should see Genuine next to Display.

I believe this software-based verification should be done prior to visual assessments, as a good-quality third-party screen can sometimes look convincing.

Parts and Service History

Apple has display repair information for iPhone 11 and beyond, excluding iPhone SE (2nd and 3rd generation).

You might see:

• Authentic: Genuine Apple part and repair process
• Unknown: The part may not be genuine, modified, unverified, or functioning properly
• Used: Genuine part previously used in another iPhone and supports newer models
• Repair Incomplete: New part placed, but repair procedure not complete

Apple says that if a component has been serviced several times, only the most recent service will be shown.

Physical Checks at the Screen

Physical inspection can give you hints but not proof of authenticity.

Search for:

• Uniform brightness across the display
• Natural-looking, realistic colours
• Altered screen alignment
• Responsive, smooth touch
• No weird bezels surrounding the screen
• Standard viewing angles

Feature Testing

Test features requiring proper display performance:

• Drag an app icon around the screen to see how it responds to touch.
• Typing in different keyboard locations.
• Change screen brightness.
• Use automatic brightness.
• Check True Tone, if supported.
• Test Haptic Touch.

Apple says non-genuine displays may encounter Multi-Touch issues, inaccurate colour calibration, lower maximum brightness, diminished functioning of the ambient-light sensor, and True Tone concerns.

One practical thing I would stress is that True Tone operating alone does not mean a screen is an original. Use it as a cue, not your only test.

Real vs. 3rd Party Comparison

A real Apple display is engineered and calibrated to function with iOS and conform to Apple’s standards for touch response, brightness, colour accuracy, white balance, True Tone, Night Shift, and Haptic Touch.

A third-party display might work, but quality varies a lot. You may also experience problems following an iOS update because Apple designs its hardware and software together.

Frequently asked questions (FAQs)

1. Does True Tone check the original iPhone display?

No. True Tone is a helpful indicator, but it should not be considered definitive proof.

2. Can a genuine screen be previously used?

Yes. Supported iPhones of subsequent generations may recognize a valid part that has been installed before in another iPhone as “Used.”
