Apple has announced a “iPhone 11 Display Module Replacement Program for Touch Issues.”
The company say it’s determined that a small percentage of iPhone 11 displays may stop responding to touch due to an issue with the display module. Affected devices were manufactured between November 2019 and May 2020.
If your iPhone 11 has been exhibiting this issue, please use the serial number checker here to see if your device is eligible for this program. If so, Apple or an Apple Authorized Service Provider will provide service, free of charge.
