The latest updates are: 11.1 iOS Beta 2 si iOS 11.0.3 for iPhone and iPad.
If for beta version of iOS 11.1, Apple does not offer any information about the changes made, for the iOS 11.0.3 public version, they say they are solving a series of bugs for iPhone si iPad.
Solving sound si haptic feedback for iPhone 7 si 7 iPhone Plus, and most importantly, resolving (at least for a while) touch dysfunctions for iPhone 6s devices whose screens and touch have been exchanged for Apple's unauthorized service.
As it seems, after the release of iOS 11 many owners of iPhone 6s they complained no touch functionsCPC. The issue appeared on the iPhone 6S devices that had the broken screen that was changed to Apple's unauthorized service, using Apple's un-screened screen and touch.
So in the future attention to the quality and provenance of components that are changed in service. If these are not original, it's very likely that they will no longer be compatible after an iOS update.
Can iOS updates be downloaded and installed via iTunes or directly on the iPhone or iPad via "Settings"? "General" ? "Software Update". Minimum 50% battery and Wi-Fi connection.
