Apple has issued a third update to iOS 11, with the latest fix sorting out haptics and audio on some iPhone 7 and iPhone 7 Plus devices, plus one involving non-genuine display replacement on the iPhone 6s.
It is not clear what was the root cause of the iPhone 7 family issue, nor how prevalent it was. The iPhone 6s-specific fixes a condition where an iPhone 6s would be rendered non-responsive if fixed with a third-party display.
Apple has appended an unusual note to the update, saying that third party displays may have "compromised visual quality" and may fail to work correctly. The company goes on to remind users that repairs should be done by Apple to guarantee installation materials and repair skill.
The update, weighing in at about 279MB, appears to be limited to the two fixes, much the same way that the prior two sub-point updates were restricted in scope.
On Monday, Apple released beta 2 of iOS 11.1. It is unclear if the fixes issued on Wednesday are included in that update.
