Usage Notes

  • For iPhone 13 Pro, 13 Pro Max, 14 Pro, and 14 Pro Max, the verification of True Tone is done using the cover code inside the display IC. You only need to write the cover code of the display IC and should not modify the data of the original touch IC to avoid touch IC data loss and pop-up issues.

  • The display IC has a limited number of write times, usually 3 to 5 times. If the write fails, it is likely that the limit has been exceeded, and it is not recommended to continue writing as it may damage the screen.

  • The data of the touch IC does not have a write limit and can be modified repeatedly.

  • For iPhone 12 series, 13 series, 14 Pro, and 14 Pro Max models, the verification of True Tone is done using the cover code inside the display IC. For iPhone 8-11 Pro Max, iPhone 14, and 14 Plus models, the verification of True Tone is done using the cover code inside the touch IC.

  • For iPhone 14 Pro Max, Samsung and LG screens are compatible with each other, but not all LG screens are compatible for interchangeability. You can differentiate the screen types by magnifying the area.

    Region 01 is incompatible with regions 02 and 03, while regions 02 and 03 are compatible for interchangeability.
