Litaya, A 15-year-old student have made a beautiful iOS 11 Concept. In his iOS 11 concept, he has made some better changes to Siri, Control Center, Camera, Multitasking and more you need to know. More features like Multi-Window, Multi-User and Dark Mode added in this iOS 11 concept.

What I liked in this concept is the One Hand Camera UI design. In which you can slide up or down to change the mode between Photo, Panorama, Video and more. One tap to activate, Long press for more.
Addition to Night Shift Mode, Apple must have to add the Dark Mode because it makes your eyes relaxed at the night time. You can pick a different paper as well according to this concept.
Litaya has redesigned the Today page by adding One place for Siri Suggestions. it really helps because Siri can offer you a specific app action according to your taste and demand.
