No True Tone After iPhone Screen Replacement
Problem:
There is no true tone on an iPhone X / 11 / 12 after a screen replacement or there is intermittent touch glitches / ghost touching/
When replacing an iPhone display, be it a genuine or an aftermarket, certain information is stored on the display. As you can see in the photo below, the display was replaced without transferring the data and True Tone is not available.
Solution:
The data from the original screen must be copied to the the new / replacement screen using a special read / write tool to avoid losing True Tone or experiencing touch issues after 1-2 months.
If this is an issue you have experienced, take the phone back to the repair shop and asked for the data to be transferred, if they do not have the machine ask for the original broken screen and take it along with your iPhone to a professional repair shop that can do the migration.
