iOS 11 blocks some iPhones after installation, according to some specialists in the repair of Apple products, and the problem seems to be quite disturbing for many people. For now, it is not confirmed that it would be a problem that affects a very large number of users who have installed iOS 11 on iPhone 6S, but those who have their screens replaced with some counterfeit ones seem to have problems running the new version of iOS.
iOS 11 seems to completely block the screens of iPhone 6S phones, practically rendering the devices completely useless since you can't see what you're doing on them. Many types of components that can be used for iPhone and iPad are sold in China, including screens that are not manufactured by Apple, and iOS 11 seems to completely block some of them, without users actually knowing what is happening .
iOS 11 affects some or all iPhone 6S phones that have counterfeit screens installed in unauthorized services, so there is a risk for anyone who has done such an operation. It is not known if there are counterfeit screens from certain manufacturers that are blocked by iOS 11, or all of them, and this is because the number of those affected outside of Asia is not very large, so the data is quite small for now.
iOS 11 could, through this change, implement a security measure that aims to prevent the replacement of damaged screens with counterfeit ones. For now, it is recommended that all those who replaced their original screen with a counterfeit one not to install iOS 11, and if you don't know what kind of screen the broken one was replaced with in an unauthorized service, you don't really have anything to do but you risk it.
