Apple has acknowledged widespread problems with the displays on iPhone 11 handsets and says that it will replace them for free.
“Apple has determined that a small percentage of iPhone 11 displays may stop responding to touch due to an issue with the display module,” an Apple support notice explains. “Affected devices were manufactured between November 2019 and May 2020.”
Not sure about the “small percentage,” but given the date range, it’s fair to believe that millions if not tens of millions of iPhone 11s are impacted by this issue.
Own an iPhone 11? You can use an Apple serial number checker on the Apple Support website to determine if your iPhone 11 is eligible. If so, Apple says that it or an Apple Authorized Service Provider will replace the display free of charge.
If you previously paid to replace an iPhone 11 display, contact Apple about getting a refund.
