iOS 11 is in Beta test , you can give it a try !
Apple released a Beta version of IOS 11 not only available for developers but also for iPhone owner , you can get the Update downloaded from Apple’s website . I wouldn’t recommend you to download it anywhere else . This version has couples of improvement as usual such as ;
Option to drag and drop info and media across apps, expand the dock on iPad to fit far more apps, multitask with up to three apps simultaneously, and access a more traditional file management system that syncs with iCloud and other third-party providers. There’s also a host of smaller changes that should prove useful, including built-in screen capture, a more robust and customizable Control Center layout, and Siri language translations.
Trust me the only reason that makes Apple bringing updates for its IOS is to make iPhones , iPad and MAC more secured and safer .
