For old users, the ability to upgrade the new system is a very exciting thing, after all, upgrading the system often allows the old machine experience smoother and more stable. However, for iphone 6s users, IOS 11 has been upgraded for some time and has been updated multiple times, but the overall experience is not ideal, such as the endurance problem.
Even more so for iphone 6s users to crash, Apple officially shut down its iOS 10.3.3 downgrade channel late yesterday. If the iphone 6s users did not have time to downgrade, they would have to stay in the iOS 11 system version. Shortly after the release of IOS 11, Apple shut down all models of the system’s degraded channel, when the iphone 6s became the only survivor, but now the phone’s posterior route has been ruthlessly blocked by Apple.
There are many iphone 6s users who are upgrading iOS 11 complaining about frequent problems, the biggest slot is the system cotton obvious, fluency is not even as good as iOS 10, which is also a lot of friends around the reluctant to upgrade iOS 11 the main reason.
