On Tuesday, Apple released an update to iOS 11 that claims to fix some iPhone 8 touchscreens that had recently become unresponsive.

Some iPhone 8 owners that had their displays repaired by third parties noticed their touchscreens became responsive after the previous iOS 11.3 update rolled out. The new update, iOS 11.3.1, will reportedly fix this issue.

In its release notes, Apple also warns users against using "non-genuine replacement displays." According to Apple, these third-party parts are to blame for the difficulties experienced by iPhone 8 users.
