IOS 11 is announcing to be an interesting system but without giving it back. At least that's what I concluded after testing iOS 11 Public Beta for iPhone si iPad. Currently, tested on a iPad Mini 4, IOS 11 did not impress us at all. There are many times when the system remains stuck in the menus, there is no possibility to Closes all open applications simultaneously, and in addition, they often do not even close one by one. It is probably the most installable iOS version Beta, ever released by Apple.
However, we have no cause for concern. It is a testing and development system, and users who have installed iOS 11 Beta, I can pass the latest stable iOS version, 10.3.2 version at this time. We hope to receive in a few days 10.3.3 version which passed by Beta 7 at this time.
How can we downgrade from iOS 11 to iOS 10.3.2 / iOS 10.3.3 - Install iOS 10.3.2 on iPhone and iPad
First of all, make sure we have one Windows PC or Mac With a latest version of iTunes Installed and o Internet connection.
