Apple is being sued by owners of Apple's iPhone 6 and 6 Plus phones, over unresponsive touchscreens, reported Reuters on Monday.
The issue, first widely reported by tech site iFixit, is said to affect last-generation iPhones and manifests itself as "a gray, flickering bar at the top of the display and an unresponsive touchscreen."
The iFixit report says: "Of course, there's no way to tell exactly how many phones are afflicted with what we're calling Touch Disease, but every repair tech we spoke to told us that the problem is incredibly common."
The plaintiffs in the case, filed as Davidson et al v. Apple Inc., accuse Apple of violating California consumer protection laws and are seeking unspecified damages, Reuters said. The class action suit was filed August 27.
Apple did not immediately respond to a request for comment.
