Here are some methods to check if an iPhone has an original or non-Apple display:

  1. Check the color and brightness: If the display is not as bright or the colors are not accurate, it could indicate a non-Apple display.

  2. Check the font: Apple uses a specific font on their displays, so if the text on the phone looks different or unusual, it could indicate a non-Apple display.

  3. Look for the Apple logo: The Apple logo should be visible on the display. If it is missing or looks different, it could indicate a non-Apple display.

  4. Use a magnifying glass: Examine the display using a magnifying glass. If you see any pixels that are not uniform in color or shape, it could indicate a non-Apple display.

  5. Check the touch responsiveness: If the touch responsiveness is not smooth or accurate, it could indicate a non-Apple display.

  6. Check the serial number: You can check the serial number of the iPhone in the Settings app. If the serial number does not match the one on the device, it could indicate a non-Apple display.

  7. First, remove any screen protector that may be on the display. Next, illuminate the display with an LED flashlight positioned at least one foot (30 cm) from the display.

    If the reflection appears like the image on the left, then the display is likely a non-Apple part. If the reflection appears like the image on the right, with color bands or refractive color banding, then the display may be a genuine Apple part or may still be a non-Apple part

    Note: This test only checks for one specific display modification.

    Another way to check is to inspect the sides of the display that fit into the housing of the device. Non-Apple displays may not fit well on the case, and the display may be slightly misaligned compared to an original display. It can be helpful to compare the device with another one to check for any differences.

It is important to note that it can be challenging to identify a non-Apple display, and it is always best to have the device inspected by an authorized Apple technician. Using a non-Apple display can also void the warranty on your iPhone.
